This reminds me of other DOS screensavers. (I think the first
screen saver was invented for Norton Commander by John Socha.)

DOS Navigator (freeware w/ srcs) had some external screensavers
(non-TSR). How big do you want it? Are you trying to do "demo"
graphics effects?

FreeDOS FDAPM also has IDLEDPMS (TSR) for newer monitors:

Although bloated (20 kb footprint), there was also Starry Night
TSR (w/ .ASM source):

Wolfware/WASM assembler had various examples, including Sleeper
TSR (VGA; also EGA and MDA variants):
