How To: Turn Your Google Camera Lens Blur Photos into Parallax Images

Google's new camera, aptly named Google Camera, has been all the rage since it was released onto Google Play last Friday. The main reason is the amazing Lens Blur feature that adds depth-of-field Lytro effects to photos, without the use of any expensive accessories or extra hardware, like on the new HTC One M8.

How To: Play Sonic the Hedgehog & Other Classic Sega Genesis Games on Your Nexus 7 Tablet

A blue hedgehog runs at high-speed through fantasy environments collecting rings. Sounds a bit loony, but I’m of course taking about the Sonic adventure series that was made popular on the Sega Genesis. The days of cartridge 16-bit gaming has long been eclipsed, but nostalgia can get the better of the old generation of gamers.

How To: The Fastest Way to Share Large Files from a Nexus 7 to a Samsung Galaxy S3 or Other Android Device

Recently, I wanted to share a large video file from my Nexus 7 to my friend's Samsung Galaxy S3, and even though he was standing right next to me, it was an extremely difficult and frustrating thing to do.

When I wasn’t in school, you could usually find me at the arcade playing Street Fighter, The King of Fighters and Marvel vs. Capcom. At home, I had my Super Nintendo and Super Mario World keeping me glued to the television until the next boss stage.
