It is 8mm Endlighten (0N002 XL) with a 5mm rear-projection acrylic sheet (7D006 RP) on top. Don’t have any experiences with the opal30, sorry.

In the DSI set up what did use to glue the two layers together or was there any other layer between the two acrylic sheets at all?

thats a good question, and how do u get such good blob tracking, our cam picks up the projected image and thinks that they , the boxes or sliders are the touch point and then give them ids?
and opal 30 may be relitvly cheap but it scratches easy.
