I’m not sure if this post belongs here or in MPSIMS.
I’ve been sick for almost a week now, so I’ve had a lot of time off work. During that time, I’ve gotten hooked on making snowflakes on SnowDays: http://snowdays.me/
I think I may have posted a link to SnowDays many years before. I’d forgotten about it until a few days ago. I’m glad I stumbled across it again! Enjoy.
