Create symmetrical paintings! You can only draw on the left side. When you're done, press space to fold over the paper and "print" your design onto the other side! Click on the paint on the bottom right to change the paint colour. Remember in nursery/playgroup/preschool/sgoil-àraich/kindergarten/whatever, when you made symmetrical butterfly paintings by painting on one half of a sheet of paper, then folding it in on itself so the design printed on the other side, then opening it up? Well, this is a digital version of that!
