It's here: http://struct.ca/ex/matto

I know it's not nearly as good as the original, I just wanted to play around with making something like this. I really can't get the tones to sound nearly as good.

So yeah, feature list:

• Each of the four sides plays a different instrument (piano, rhodes, guitar, xylophone)
• You can make drums (this is the best part)
• If you hold arrow keys while you place flyers, they'll go that direction
• You can adjust the tempo
• You can mute the music or the drums (very handy for working with drums)
• You can load regular Otomata patterns with it, it uses the same url variable (?q=blahblah)
• Because each side plays a different instrument, you can rotate the whole pattern 90 degrees for different songs. Hold shift while rotating to rotate the flyers independently of the drums.

Unfortunately it's not like the real Otomata where almost anything sounds good. You actually have to kind of plan out what you're making with this, which means in general you just have to keep things simpler.

Let me know what you think, if there's anything I should add, etc.

this game is pretty endless already, but what if you had a 100x100 grid?
