All right people, time for a new challenge. I was thinking about something weather related: rain, snow, lightning... that kind of things (it's going to be Christmas soon...). What do you think? :)

was gonna say be more specific - cos that kinda includes an awful lot. snow is a thing by itself and we've just had elctric(lightning) on kirupa.

But yep - count me in.

I know I've tried to get a few challenges going recently but can't seem to get anything. I started a 3d challenge , then a paint dripping contest - but don't think I hardly got a response (and when a response came with the 3d challenge it was weeks later)

What about an open challenge - on any subject - that might generate a bit of interest?

having said that I haven't done anything for this.

Thunder version betafunction makeLightning () {

}
}Dark background, and click.
