Sticky notes are among the handiest of office accessories. Not only do they allow you to slap a note almost anywhere (both to yourself, or someone else), but they can even be used as a form of art. Don’t believe me? Leave someone in a cubicle for 8 hours with nothing to do and a couple pads of Post-Its. Well if you want a set of sticky notes that can be used as art (in addition to their primary function), you should check out these Block Notes.

As you might have noticed, these blocks look very familiar. That would be because they are the same shapes used in the game Tetris. Sure, they are a bit small to use for long messages, but for a quick note here or there, they could be fun to use. And with 100 of each of the 8 shapes for just $10, you can really have some fun arranging the shapes on your office wall.
