It looks like the reflection is almost a blue tube. If this is only 1/2 of a larger unit, maybe it fits inside of the game piece? I've attached a REALLY LOUSY photoshopped image of what the other half might look like. Basically, I think that it could fit over the current lexan and be secured by bolts or something - this would explain the holes in the lexan....
Then again, maybe I'm just nuts!
