Sorry Mark, I couldn't get to yoour's. I tried Robert's, and now my keyboard is all sticky. Dammit Bill, yes, I mean the ribbon candy one!

Hey, nice ribbon candy and I actually did try the "softening" effect aurora. All good stuff to showcase what can be done with QB64, if you have the artistic ability to create it. Me, I'm still working on a fill function for blocks. Oh well...

Aurora and Ribbon Candy by rfrost@mail.com and Aurora-Mod by bplus look all interesting.

To show guests, who otherwise have to imagine the beauty directly from code,  I made a very short (a few seconds, but still takes nearly 14 MB after reducing from 74 MB) GIF-Animation from the Aurora-Mod.

Interesting. I was thinking of making a gif of Marks fireworks program I have software that can record from the screen, but I'm curious, what did you use to convert to a .gif?

I use GIF Movie Gear (Full version).
It is a little bit old, supports Windows XP, but works fine with Windows 10.

I really like first part of Richard Frost's ribbon candy.

It reminds me of an experiment I've been meaning to try but keep getting distracted. Stay tuned...

That softening Bplus did makes it way more realistic. 

But it's too dim.

It works better if you plug it in.

I agree, softening makes it more realistic, but brighter would be better.
