Otherwise have a play with neon logic https://lucsmall.com/2016/10/08/neon-ring-counters/

Sounds tedious but you could build an array:  20 by 20 would be nice.  Make each 555 station accept pulses from its neighbor(s), and emit next pulse to another neighbor, producing a 'wave' propagating from station to station.  One option keeps separate directions, another just blast transmits to all close neighbors.   (Starts to look like a researcher for neurological function brain / vision)

That is a rather famous research project which has been published in many places.  The original version used ordinary 555 chips.  It was called "firefly" and showed how gradually all the individual units would drift towards flashing in synch.  That is certainly what I would do with hundreds of 555 chips.

From the webpage:
If only have they marked it "CN555" with proper data-sheet - it would have been totally legitimate and fair product.

Now to the original question: I do like RJHayward's and RCrowley's suggestion. That would be an awesome project. Wiring it would be very tedious, though.
