I have no perks worth this number and I am not going to invent any. So, simply: a personal thank you from me, and your name in a lasting spot among the people this site thanks. Everything else becomes build time. Includes previous tiers.

WHERE SUPPORT GOES

SkyTales is one person. The infrastructure is cheap: roughly a jump ticket a month. That is not where support goes.

It goes into time. The physics, the numerics, getting a simulation to run smoothly in a browser tab. All of it is hours, and hours are the one thing this project runs on. Support converts into build time. Everything here was free before you arrived and stays free either way. Support changes the rate, not the access.

FAQ

Can I use the visualizations without supporting?
Yes. The visualizations are free for everyone. That is the model, not a promotion. Support adds things around them; it never unlocks them.
Can I use the source code in my own projects?
No. Source access is for reading and learning. Copyright stays with me: no copying, reuse, or redistribution. If you want to license code commercially, email me
Can I support with a one time payment?
Yes. Make a one‑time donation here.
I'm a teacher. Can I use these in my classroom?
Please do. That's the whole point. All visualizations are browser based, so they work on any device. To keep it academic, I added a citation at the index of the site.
What tools do you use to build these?
JavaScript, WebGL, Three.js, and a lot of math.
