I found a site that has a decent web based editor and templates for many instruments and electronic devices. It's Style Flip: DJ Skins, Pro Audio Skins, iPod Skins, Laptop Skins, Keyboard Skins this might be fun for some one who creates digibash pics but if you just want to create at tf theme there is tons of artwork available here. For best results prep your design objects at a more advanced web based graphics editor like pixlr.com. It helps to have things on separate transparent layers to adjust around button and knob placement. I know I put soundwave on an autobot grid. It just looked better.
