You spend hours, days, weeks, and even months placing each of those pixels with love and care (Or wildly and hateful ).  Pixel Blocks will now allow you to take that pixelized masterpiece of yours and make it real.  Well, as real as it can get...  You can get up to 20 colors, and even a greyscale kit.  Don't mistake these for Legos, they only come in single pixels, and the can be connected top to bottom, or side to side.

After some investigation, I found the best price for a kit of 200 blocks of one color is the cheapest at their site, and the other kits are cheapest at the Exploratorium Store.  The also have a list of places retailers in the USA/Canada.

Great idea if you want to do some pixel art if your power goes out.
