Does anyone know of a web site where I can download a 3D video clip for my elsa revelator glasses? I've never seen one.

The main trouble with ELSA relevator is the
proprietary solution for givng commnds to the glasses. The result is, that it is incompatible with a lot of thing. You can make an hombrew min-DIN3 conector to connect the glasses with the pararel or serial port and make it compatible with Winx3D library. You can then use an watch movies + use software described on my www:

Description of the pararel to DIN-3 conector given by David Qualman folows:

Yes, it seems possible to build such an adapter. For the 3D-SPEX
driver, I raise all data lines on the parallel port high, except for the
control line. This is data bit 2, or pin 4 of the parallel port. You
could wire this pin 4 to be the eye controller of a VESA connector. I
don't think that a single bit on the parallel port could provide enough
current to drive the glasses, since each can only provide 3 mA. The
remaining 7 pins could give a total of 21 mA, which may be enough. Don't
just tie the 7 wires together however, or you may end up shorting
something out. My recommendation is to use a power supply, or a wall
brick, instead of using the parallel port, for power..

Triggering glasses over the parallel or serial port yields the same problems as the Revelator trigger, i.e. software incompatibility, IRQ-conflicts, CPU-overhead.

The only recommended homebrew controllers are VGA-pass-throughs!
