I was testing random stuff
So here is a happy rainbow kinda thingie!

Actually the rainbow is animated and flows to the right nicely
This uses the Tiled Sprite plugin SirG
I'm not sure I'll use this for my project because the fps are dropping fast with many nodes, but it could be super handy to create all kind of moving things, escalators, hydraulic pipes, tank tracks, conveyor belts...
