Currently using Odyssey 1.23 r5 on OS 4.1u3 on my MicroA1. The snow flakes don't kill my system, but I eventually get a message about can't allocate RAM. This happens if I scroll up and down the webpage window a few times with the mouse wheel. I get this same message at some other websites, so it is probably not directly related to the snow flakes. More likely I am running near the limit of usable memory. In past years, snow flakes at amigans website defininately killed my system. No snow flakes there so far this year.
I like the suggestion of static display of coloured lights rather than moving snow flakes.
Cheers,
