Nearly everyone who’s familiar with electronic games has heard of Tetris, and ThinkGeek has capitalized on this to make a nostalgia-inspiring Tetris Stackable LED Desk Lamp. You can customize your lamp into various configurations using the seven interlocking pieces, which are of course, shaped like classic Tetris shapes. The base shape is the four-block straight piece, and any piece put on there will light up in a different color. The lamp plugs into a wall outlet just like any other, and its dimensions are based on how you put together the pieces. For just $39.99 you can relive your fond memories of Tetris, except this time in real life.
