I made a quick little animation diversion for a brisk Sunday afternoon.

The EURion constellation is a pattern of symbols incorporated into a number of banknote designs worldwide since about 1996. It is added to help imaging software detect the presence of a banknote in a digital image. Such software can then block the user from reproducing banknotes to prevent counterfeiting using colour photocopiers. However, recent research shows that the EURion constellation may just be one of many factors used to detect currency, and is not necessarily required.
