Ok, if you think about, you can see why the upright hand in the back is also a right hand— this is the “mirror paradox”, that you’re not reversed in a pair of mirrors meeting in a right angle. So why is the ipad backwards?
Another Tooti Tooti video up! Make your own symmetrical designs from a plain envelope. youtube.com/watch?v=5MihLM…

L1 rolls up into L2, just as L3 rolls into ideal hypercubes, etc, limiting to the #lamplightergroup #mathbun #geometricgrouptheory
The lamplighter group as a limit of groups: L1 is drawn on ideal squares in H2. L2, shown here sits on ideal cubes in H3. Rolling these up by the next relator for L3 gives a graph on ideal hypercubes in H4, etc, Limiting to the #lamplightergroup #symmetry #mathbun
This one takes quite a bit of explanation #mathbun
