From DS9 'Blood Oath'.
As I recall, this was a VI or VII body with Playmates tric stickers applied (note the difference in size between the stickers and the recesses).
I've always loved this one- seems like a tric specifically for more military uses- hence the 'motion tracker' application. The prop had a real-time animated graphic screen built in. In early 90s tech this would certainly mean there had to be some sort of power/data connection snaking down the actor's arm. We did similar tricks with small flat screen monitors built into props for seaQuest DSV around the same time. Notice also in this pics that there are no blinkie details on the end of the tric- another hint that there wasn't room for anything else inside the shell besides the tiny monitor. In all shots other than the above close-up, a standard VII prop was used, front blinkies and all.
Seems like a lot of trouble to go to for what was essentially a single 4-second close up. I'm betting this was someone's pet project at the time- a way to see if they could have trics with real-time graphics instead of just dancing LEDs or burning in something in post production.
I'd still love to make one of these- there are more options nowadays for putting a larger animated screen inside without external leads.
