These .st also work in 3.7 and 3.8. Just file them in and in a Workspace do: FireworksAnimation start.

Had to change Rocket>>die to use Float>>pi as 3.7 and 3.8 don't have Float>>twoPi though the constant Twopi is defined in Float.

With you kind permission I'll look at it anyway :-)) It's small and cute and I believe I can understand it with little effort. Looks like a fun target to practise my (barely existing) refactoring skills.

Sure. Have fun with it. This is like something scribbled on a napkin and passed along for a good laugh and others can add their ideas if they want. You can change many things to see what happens, e.g. how long (relative to their lifetime) the rockets accelerate, the distribution of the flares or ... A nice effect is also if you have short lived flares, that create new flares when they burn out.

Thanks for making this work in 3.7 and 3.8!

Nice!

This should also work, but no guaranties...

No, it does not, at least not with the Squeakland plugin image.
