Adjust the sliders and press space. #1: I couldn't do the entire screen (apparently scratch has a list size limit.) (TBF the lists can get crazy big and there's really no reason to have lists so large.) #2: This is a really simple demo of the Index Position Equation. Realistically, this could be iterated on much more efficiently by using a smaller grid and more interesting mechanics. (EG: spreading colors or the game of life.) #3: Gets laggy. It could be fixed by only checking updated pixels as opposed to all pixels AND giving the equation boundaries (so that it doesn't error trying to change values that don't exist.) #4: Sometimes pressing space doesn't do anything. (I have no idea why) (just keep pressing it, eventually something will happen.)
