I just felt it necessary to point out that although these might
look like shadebobs, they're really not. A true demo coder would be
horrified at the prospect of iterating over each tail segment, the

framebuffer to simulate a huge tail animating.
What exactly, is a shadebob?
The term comes from the demo scene, where coders competed against each
other to produce the most exciting realtime graphical demonstrations
possible using the least resources. There are many subgenres but a
typical example would be a 4096 byte executable that when run,
produced an A/V show made up of many different parts, one of which
could be a shadebob - a ball flying around the screen leaving a trail
behind it, something that would have been computationally prohibitive
back in the 80s when the demo scene flourished.
