I'll post some pics tomorrow.....
I made a shelf out of a piece of acrylic, and used 2 small (heater) suction cups....placed the Xenia and rock on the 'shelf' next to the glass, and it moved to the glass (and back wall) by itself.
Only problem is......it keeps climbing to the top.
As for fragging....the last piece I fragged, I sliced it off the back wall and used a rubber band to hold it to the rock. It attached in a couple of days.
