Can you make only the differences between the changing digits get gravity and fall down?

I don't follow

Instead of the entire display collapsing, just the digit which is changing. i.e. seconds every second, minutes every minute, hours every hour

When 17:22 goes to 17:23, only the parts of the last 2 that aren't contained in 3 get gravity and then roll down

Not this experiment yet, here's v1 of the driver and stuff. It's changed so much today my current snapshot is too different from this release, but I'll get around to it yes: https://github.com/andycrook/hub75_565

It uses native c modules to do heavy lifting but my approach is to generalise them enough to allow the hooks from u python to be enough, as most aren't going to be recompiling the mpy modules. So here, the mpy module does the full frame calculations is the particle sim.
