After I closed my nice big studio and hit the road, I aimed my "need to create" at the digital camera and the portable computer ...handy tools while in gypsy mode.  A genius, long time friend of mine, a guy who has known computers since they encompassed an entire room, patiently and enthusiastically began teaching me how to use graphics programs.  I'm still traveling the learning curve after a decade, but wow,   it is fun!
