Reguested Application.
How about a portable slide show application similar to Slide Show Pilot.
(http://www.colorpilot.com/slideshow.html)
With similar features such as:
Most image file formats,
Create auto run CD/DVD album for PC and players (watch through TV).
Create .exe show
Create HTML Web galleries
Transitions
Add sound and music
And any other features that you wizards can think of.
And of course open source.
All on a USB stick.
