Music used:
Cat Circus - Doug Maxwell
Always Remember to Never Forget - The Whole Other
Yoga style - Chris Haugen
In the video, the simulations were sometimes paused to relieve the YouTube compression algorithm and the viewers’ eyes a bit.
Did I forget anything? Let me know and I’ll set it straight.
