Now you can custom-design your own Tetris blocks with images and even animated gifs, with GIFtris. Upload your images for each shape, save it, and play it! The moving images can be disorienting, as you can see from my first poor attempt to play the Neatorama edition here. You can play this version, or make your own! And if you do, leave us a link so we can see it. -via b3ta
