My 5th grade summer was probably the palest I've ever been thanks to one little word: Tetris. (Just typing the word makes me grin!) It just so happens that 5th grade was the summer I got my first Gameboy, and while my overall athleticism quickly dwindled, my thumbs went through the sort of rigorous conditioning you only expect from Russian gymnasts, Kentucky-bred racehorses, and moderate steroid users. In any case, all that's to say, I loved me some Tetris, so you can imagine my giddiness over seeing this over at ProductDose-- Tetris-shaped shelves! Of course, with each individual shelf costing $600, you'll have plenty of time to figure out how to line up the next block on your wall. Click here to learn more.
