Well, I guess Adobe is in no danger of a LiveCode application competitor
then. /joke   I would love to be able to join the points of multiple
visible poly shapes, for creative endeavors without relying on separate
graphics software.  Unless RunRev themselves implement an auto-trace
feature some day, eventually, perhaps on some future roadmap.

That sounds logical.

Please replace "frivolous" above with "freaking awesome".  That bouncing
line and exploding circle trick would be excellent in a screensaver.
