Hi there,
I have developed a presenter screen that can be used for teaching, advertising, entertainment and other purposes. It's only 3 prims and it has a nice HUD to control the picture switching. The HUD can be passed to other avatars that can be authorized to control the screen as well as the owner.
Find a short 5 minute video that demonstrate the features of this little gadget:
