When the problem occurs, there is a message to the console that says: "thread blocked indefinitely".
I can reproduce this on OS X with ghc-6.4.2, X11-1.1 and HGL-3.1. The console message is rare but I also got it once. This looks like a bug in HGL, perhaps some issue with polling the event queue in a threaded fashion.
Thanks very much for checking this on a different platform and GHC. I filed a bug report with the HGL maintainer.
p.s. Any stylistic or other comments about the code welcome too.
It might also be a good idea not to mess with trigonometry when creating the snowflake.
Yes, that is much cleaner.
The following code demonstrates this.
Your solution is very elegant, and a big improvement over my messy first solution. Thanks for the very instructive code! Regards, Calvin
