Teleporting robot vacuum cleaner...

Having fun on this, prompted by bluatigro's post...

My present LB 'cleaner' teleports around at random. If he lands on dirt, he removes all in that connected patch then 'ports off elsewhere. The lines show where he 'ports. Yellow would be replaced by grey but it is boring seeing the dust disappear. I'll probably add some randomly re-appearing new dust. Will put code up on my site when I have a more complete version.

Other strategies, more realisable, are head off in random direction in a straight line until dirt or boundary is met; spiral path; raster path. Keep me happy for a while....

An animated GIF of the latest version.

It demonstrates the ability to do more than flood TO a border or THROUGHOUT a color area. But of course pretty slow. Hypnotic to watch it fill in real time! Using the dll call wouldn't work here- may try working on an in-memory image....
