The other day I was playing Fez when I was reminded of an old memory game I used to play where a sequence of colours are shown and the player has to repeat the sequence correctly to proceed. Players are shown increasingly long sequences or colours, stretching their memory to its limits!

Back in the old days, there was an operating system named after transparent, glass-filled wall apertures numbering in mid-90’s. This operating system was designed to run on computers with CRT screens, which actually needed software to upset the patterns of light they generated, called screensavers.

This operating system had just such software, in a number of different variations. One of these created the “illusion” that the observer was travelling through space, passing stars. This is the subject of this week’s challenge.
