It's once again Monday, which means it's time to highlight some of the most recent community submissions posted to the Math Craft corkboard. Since two of these posts were on polyhedral versions of M.C. Escher's tessellations, I thought we'd take a look at building a simple tessellated cube based off of imitations of his imagery.

A simple method for trimming natural hair that does not get worn straight. Invest in a pair of hair cutting scissors. They are fairly cheap and available at Sally's and Walmart.
Scrabble is definitely my pastime addiction of choice, but it's not the only game I frequent. I'm a big chess fan, crossword lover, and hooked on puzzles—any kind of puzzles. Logic puzzles, sudoko, and... the Rubik's Cube.
Ever think you're spending too much time on your Mac? Ever want to actually see how long you've been on certain apps? Well, that's exactly what Time Sink by Many Tricks tells you.
The seated hammer curl using resistance bands is used to target primarily the biceps, however because the wrist remains perpendicular to the ground rather than parallel, the forearm also gets a workout.
The push-up is one of the most recognizable upper body exercises. Push-ups are generally done to work the chest muscles. However, close grip push-ups primarily work the triceps. The following are instructions for performing the close grip push-up:
Good mornings are used primarily to work the lower back muscles. The hamstrings and gluteus muscles are also involved in the movement.
The reverse barbell shrug is an excellent way to work the trapezius muscles. This exercise is sometimes referred to as "behind-the-back shrugs." The reverse shrug minimizes the momentum that can be generated with traditional shrugs to the front of the body.
This curl up is commonly used to test abdominal endurance. Many fitness certifying organizations use the curl up as a protocol for exercise testing. This exercise is similar to the abdominal crunch. However, the range of motion is greater than the crunch.
This exercise is great for shaping and strengthening the chest muscles. The chest is scientifically named the pectoralis. This muscle is used any time you push a chair up to the table, shut a car door, or push a shopping cart. There are two muscles that make up the pectoralis. They are the pectoralis major and minor. The pectoralis major is always the prime mover during chest exercises.
The seated chest press can be done from any chair with a seat back. This exercise is great for shaping and strengthening the chest muscles. The chest is scientifically named the pectoralis. This muscle is used any time you push a chair up to the table, shut a car door, or push a shopping cart. There are two muscles that make up the pectoralis. They are the pectoralis major and minor. The pectoralis major is always the prime mover during chest exercises.
Here is an exercise that really works the gluteus muscles. It is relatively easy to perform. However, for this exercise to be effective, it does require a bit of skill and proper technique. A workout mat is recommended.
The reverse leg kick is perfect for working the glutes/butt. It is very easy to perform, and is one of the few exercises that works the glute muscles exclusively [with assistance from the hamstring muscles].
The step-up is a great exercise for the muscles of the upper leg. It effectively works the thighs, hips, and butt. The calf muscles work as synergists during the step-up exercise. They assist with balance. The step-up exercise can either be done one leg at a time or alternating between legs.
The crossover lunge is an advanced exercise that is used to build strength and improve flexibility in the muscles that act on the hips and thighs. The crossover step is often used as a warm-up to prepare for more dynamic exercises or sports conditioning drills.
Mike received a tiny medical pill-camera from a relative who had recently undergone treatment. The most surprising part apart from the utter grossness is that the camera transmits electrical signals straight through the human body to skin electrodes with no radio at all! Check out the video to see the camera and Mike's impressive mastery of the oscilloscope.
I know, I know, you've probably seen entries about Theo Jansen's Strandbeests here before, but this goes straight to his url and has the smoothest video I've seen of them yet.

With all the great cakes on the site, I thought I'd share one from my collection. Straight from the Make Balloon Animals World, I wanted to share this giant balloon birthday cake. This gentleman got his wish for his birthday... A giant cake AND the girl of his dreams.

Happy Turkey day, Yanks! Mike from thesubstream is finding it very hard to NOT recommend you go see Dwayne "The Rock Master" Johnson in the straight-up, no-laugh old-school action flick Faster.
Only two weeks left to submit your pranks to the Jackass 3D Prank Contest. Don't miss the chance to pull pranks with Johnny Knoxville himself!
I like checking the ferry cam in order to try to minimize the wait up the hill. Nothing beats driving straight onto the ferry (except maybe being the last car on the ferry).
Children think that a line is a line. Usually a straight line. This video shows children that there are different types of lines. Show your child different types of lines.
This video explains how to construct a model of a geodesic dome from paper and shows how to draw triangles with a compass and straight edge. Construct a model of a geodesic dome.
Good posture is more important than pleasing your mother. A lifetime of bad posture basically ensures spine complications, back pain, muscle aches, and other not-so-pleasant physical health problems.
Fractals and stars are two of the most beautiful and complicated-looking classes of geometric objects out there. We're going to explore these objects and how to carve them on a pumpkin. Unlike the last one on carving polyhedral pumpkins, where we used the entire pumpkin to carve a 3 dimensional shape, the pumkin carving in this post will involve two-dimensional images on a small part of the pumpkin's surface.
In honor of the new Astronomy World, I thought we should look at a few planetary icosahedrons. The icosahedron is the most round of the Platonic solids with twenty faces, thus has the smallest dihedral angles. This allows it to unfold into a flat map with a reasonably acceptable amount of distortion. In fact, Buckminster Fuller tried to popularize the polyhedral globe/map concept with his Dymaxion Map.

There are several ways you can go about creating your NURBS helix curve in Maya; I will demonstrate the two easiest ones.

The sudden deceleration, shifting in the knee, popping sound and screaming from the intense pain that immediately follows is becoming increasingly common among our young athletes. Those who have witnessed or suffered a torn anterior cruciate ligament (ACL) are familiar with the pain, surgery and intense 6 to 8 month rehabilitation that accompanies the injury, not to mention the disappointment of ending a season. Nationwide, this will occur more than 500,000 times this year, and female athlete...

Here's another Back to Karkand achievement guide for Battlefield 3. This one is for 'Third Tour', which requires you to get a kill using only the BTR-90, DPV, and F-35. Oh, these are all vehicles by the way, so you know this is going to be a fun one.
Deadshot is one of my all-time favorite Batman villains. So when I saw that he was in Batman: Arkham City, I jumped on this sidequest faster than I jump on a fresh batch of cornbread. Don't judge me, I'm from Indiana.
I've been pretty straight forward with my praise for Batman: Arkham City. But the thing I like most of all are all of the side missions in the game. One of the cooler, and darker, ones is entitled Identity Thief. No, you don't go after some nerd that hacks people's credit card information. You go after a psychopathic serial killer.
