Something to try...

I was aiming for a TV with this digital collage, but somehow it got away from me and ended up looking like a psychedelic Etch A Sketch—minus the controls.
Somewhere in the mountain of stuff in our crawl space, we have one. But where could it be? Not to worry though. There seems to be a virtual equivalent for every toy going nowadays.
Check out www.etchy.org to experiment with Etch A Sketch online by using the arrows on your keyboard.
One thing that’s always disappointed me about it though is that you can only “draw” straight lines.
