Or, what to do when you've connected your K-3 to a computer with a keyboard...
1) Press the little "LV" button in the lower left corner (to turn live view off and make the camera appear "normal" again) and hand the camera to some unsuspecting victim. Now press the shutter button in Remote Capture every so often!
2) If you're really bored, use
Firebug to read the requests the Remote Capture is sending to the FluCard to make your camera do stuff. Then open a new tab and paste something like "http://pentax/cgi-bin/host_operation?action=shutter&seq=00009362" into the address bar and hit return. Repeat until it becomes funny...
3) Connect a Blackberry to the FluCard and try to do anything. You won't be laughing, but rather crying that you have a Blackberry...
I'll add more as I come up with them...
