Not only could he draw, but he built an app that allowed normal folk to draw an ink splot monster just like him. I love this app, despite the fact It hangs, and stalls, it's just beautiful.
Just look at the line options:
You can have straight, or squiggly, or more squiggly, or hairy spider or mad cobweb.
Trying to draw lines with these tools is dreadful, so just go with the flow, make an ink splot, add some pre created eyes and what not and enjoy yourself.
Then when you are done, if the app is feeling cooperative, you can use the camera to put your weird creation into the real world
All the dialogue boxes are a delight, and it hands out badges for doing stuff... you can even add speech bubbles.
It does struggle t respond, and seems like it's running out of memory, or maybe just hasn't been updated to cope with iOS8, or whatever we're on, as I remember it running ok on my old iPad 2.
I'v checked the app store and can't find it listed any more which is a shame.
