We had the same idea but wanted to go much much further. You should really try it out, its called Collusion. https://col.lu/ You have to sign up but it keeps your drawings like google docs and is real-time collaborative without the other people signing up.

Works on everything too, tablets, laptops, supports ms surface etc and is free for public drawings.

The explore page on our website also shows you what others have drawn so also check that out. https://collusionapp.com/explore

I don't know if I'd say it's really the same. There's tons of drawing apps, but this is much more of a nostalgic thing, and it's for kids.

Also, it's open source, which is a huge draw. (I'm going to be porting it to a web platform... probably tonight, I'm excited.)

Depends what you mean by kids, but actually we did a lot of work with schools and the kids love it.
