[Snap!] ultrasound

[connochaetes]

I just used successly the ultrasound library contributed by Joan Guillén and Josep Ferràndiz. (Thanks.) I aimed to try the same effect using "Snap!". Sadly, it didn 't work out. Here is the script. Is there a typo? Is the any kind of fundamental error? Any suggestions are welcome.

And: Yes, I keep in mind that the functionality under "Snap!" is under develpment. (But it 's just fun to use it.)

Closing this one as it’s related to the (now defunct) Snap! compiler. Sorry about that
