Ipad drawing app

[Thebirddk]

I have been looking around for a little while now for an app for ipad that can let try out drawing on the ipad.
I have allways seen myself as a bad drawer and i wonder what it would be like to draw on this and if it may feel different.
I would like to know if some of you know a good free app for testing drawing so i know if it's different enough for me to make something happen.

I did't know where i should post this but this seemed like the right place.
