my version of the ss mega tree was actually affordable, it has 640 smart string nodes
(i didn't buy the nodes all at once, i bought is stages - i know it's cheaper to get it all at once, but i couldnt afford it all at once.)
then, one hub, and 8 smart string controllers run it.
each string in 80 nodes, run from the bottom up 40 nodes, then double backed down to make it look like there were 16 strings.
