That's a great idea to share lists between frames,
if only j601 allowed it.
You did not have to zoom out, just change the
aspect ratio -- make the window wider.
To speed up rendering you could
- reduce sphere mesh from 10 10 to 3 3 (or 5 5)
- remove every other or two points:
L=: (#~ 1 0 0 $~ #) 0.07*I^:(<COUNT) 0 1 0
