If that's glitch art the way I understand glitch art, then it's only volatile and uncooperative because its practitioners want it to be. The majority of people I've seen glitching circuits have no understanding of what they're doing, actively resist gaining any, and then act frustrated when the humidity changes and the glitch doesn't work anymore, or the chip dies after a few more tries.

If you want a glitch to ground out a sync pulse that travels between chips in a Speak N Spell, but do so _without_ overstressing the chips and eventually destroying them, there are absolutely ways to do that. Buffers and diodes are not rocket science, and once the signals have been found, manipulating them can be made repeatable, safe, and durable.

If you want a glitch to happen somewhere between the 4th and 40th scanline of a video frame and always during the horizontal blanking interval, it's absolutely possible to construct a trigger circuit that will do precisely that, every time, perhaps still with a configurable degree of randomness but never in a way that will smoke the chips.

Which is to say, suffer for your art only if the suffering is the point. Which I suspect may actually be the case.
