"self touch", "good touch", eh? are those technical terms? :-D is this is what the nuns warned me about in grammar school?
in the pink section, the arms are connected to a seed (is that what you call them?) which goes nowhere. i didn't find any other branches and i've lost that cube due to having to reboot.
is this an oddity or a known type of structure? in the latter case, can you tell me where to find out about it? it reminds me of fixing a wire nut to the ends of live wires to protect them from touching other wires or careless human fingers. it's really cool, whatever it is.
