Tetris light and especially tetris is one of the most famous games in living memory. Now you can buy a bulb that you built just like in the game. The cool thing is that when you want you can rebuild your lamp into any shape you want. Only imagination sets limits here.
When you put on a tray it shines up through some kind of magical Russian science that we do not know (as the supplier is called electricity, however).
Note: MUST have a parent or guardian present during use
