animated open sign

I know I saw one somewhere, but cannot find it again. 

I am looking for either a animated "open" sign, or something that says "24-7", or something along those lines.

I know I saw one somewhere, and it was a neon-ish color to.

Thanks!

Sketcy-sketch has an "open" sign, but it is not animated.


It would be easy enough for someone to add a glow effect to it and put it into a character sheet for you, perhaps.
