@nazroth had a guide just taking a Coca-Cola bottle, cutting pieces of it, painting that then gluing it to the hacker's hand, this seems like a more elaborated version of the same thing, looks like a basic clear support shape, then carefully cut shapes of colored plastic glued on top of it. Nazroth's more advanced guide using a bit of brass mesh is here, i feel like you could combine the two (use the brass mesh as the support part, then glue the rectangles and shapes on it) I understand why it fell from favor but damn, i do wish people put holos in all their hackers, it's way too cool
I cut up some pieces of old blister packages and on those I glued pieces of colour filter foils I got as a gift from a friend who worked as a lighting technician in a theatre.
