Automatic Photo Slideshow in Home Dock Mode (like a pc screensaver)

[SoonerLater]

I bought the Motoroloa "Multimedia Dock" for my Droid X. To my surprise, it cannot -- that I can find -- automatically start running a slide show of my chosen source of photos as soon as it is put in Multimedia Dock Mode (when it senses the magnet on the back). I want a slide show of \sdcard\photos (not of the photos from the "Gallery" ie. \sdcard\dcim). I want it to run continuously whenever in Dock Mode unless I tap the screen, then restart after a period of inactivity (like a screensaver on a pc). Is there anything out there that will do that?
