Click the squares to change their color. Click pattern input button if you want to put in a pattern number. Take the pattern # of the pattern you want, and put it in the pattern input. Please wait a second for it to finish the pattern. Share your pattern designs in the comments!
Basically the same as v2, but with 16 BOXES!!! The hardest part of this project was all the addition I had to do with the pattern number(clicking the 16th box changes the pattern # by a ludicrous amount). Also, in this version, the pattern goes automatically, on request by Grahamio, since he had trouble determining that you had to press space.
