Happy to report successful results with the iPhone's "Brushes." With a little practice anyone can make great drawings on this app. All you need is an iPhone, a pencil, and some strong industrial or duct tape. Simply tape the iPhone to the pencil; this provides an ingenius art-handle that can also play music, show films, and make phone calls while you work. Now locate a piece of paper. Apply graphite to the paper. To erase simply turn the iPhone upside down. It's fast, simple, and fun!
