That stippled background, and particularly with the X mouse cursor, brings back memories of long waits for X to start. New software updates were always exciting because they promised newer, more interesting graphics that showcased the capabilities of the hardware. Cooler icons! Motif! New ideas! And new hardware updates were even more exciting because they were expensive to get a hold of and highly anticipated. Faster drawing speed! Better resolution! Higher color depths! You could tell on a human scale how much faster the new hardware was and where your money went.

On the topic of X nostalgia, the monospace font used in TFA appears to be Go Mono, developed for golang. To me, it is heavily evocative of the console font on Sun Microsystems SPARC gear. Brings back another flood of memories.
