It's surprising how much an undo functionality goes. I just finished implementing it and immediatley found myself drawn compelled to try to actually craft something that I put a little bit more time into. I spent maybe 5 minutes on this, trying to make more subtle effects. Having this much control over what the glitches produce is maybe a little antithetical to the philosophy of glitch art I'm realizing, but hey, it's pretty cool to be more in control of what happens. &badpaint
