There is going to be a whizzy box 2.0 coming out soon. It is a random art generator where you just whizz your mouse around the screen and see what shape you get. Just before you start, you can set the size and the colour. It can be a bit laggy sometimes. If you set the size to 0, it will just turn into average size.
You can also play a game where you can try and see what your new artwork looks like.
