This will be very neat. There have been some very cool paint apps for mobile devices such as the Iphone. I personally like Autodesk's SketchBook pro. Upload one of you favorite mobile drawings that you have created. It will be a little show and tell.
Though I don't have an iPhone just yet (I'm saving up for one!), I really like the idea of this post! Thanks for starting the discussion Quinn! I also adore the last photo you submitted. It's really awesome! :)
First things first, my index finger really hurts after drawing this -_-. Anyway, below is my try in recreating "Ghost in the Machine - Jimi Hendrix" by iri5. She creates amazing pieces with non-traditional media (cassette tapes and old film reels). Let me know what you think.
