Wow, you did that on the iphone? Did you have a pogo stick, or some sort of specialized stylus? Or did you just use your finger? I saw this last night while browsing the gallery on my iPod, and assumed this was done on a DS, because of the detail. This is amazing.
Thank you for the comment.
I am using the marketed stylus pen.
There is a thing that can be done though it is not easy to use from DS. I will open it to the public by the end of this week because it makes a new work.
