I enter a lot of design competitions for company logos using Gimp and Inkscape. Some of the entries are just PNG images like mine but some look really professional with the logo simulated on a stack of business cards in the correct perspective and with simulated embossed text and logos. The logos are also simulated on envelopes, billboards with spotlights and T-shirts.
I'm going to try to do this for my entries and I can imagine how it might be done in GIMP using, for example, the perspective tool. I would be interested to hear if anyone has tried this kind of 'client mock up' in GIMP.
Due to time constraints in the competitions I'm sure these entrants are not doing this by hand every time. My guess is it's some sort of commercial plugin for PS. It would be really cool to have one for GIMP don't you think? Although I have no idea how such things are made (predictably).
