Laser Marketplace tool, how does it work?


After having seen the Egypt educational video shared by @philiprosedale recently, I’ve looked on the market place where the pointing laser is. It appears it is here made by @Midnight
but no instructions are apparently provided.
Is it only working in VR or can be used also in desktop mode? It seems quite useful for educational purposes.


still nobody answering on how to use the laser ? In the telegram chat someone told that this was NOT the item used in the tutankhamon tomb video. Does anybody know which was the original tool?
