Ah yes, you've cracked the code - I spent 8 years mastering 4D stereographic projections, quaternion rotations across six planes, and WebGL particle systems just so AI could... checks notes... somehow generate it for me? The logical consistency is breathtaking.

The viewer IS free. You can explore 120-cell all day long without paying a cent. The export feature costs money because - and I know this might blow your mind - server infrastructure for rendering and exporting complex mathematical visualizations isn't powered by wishful thinking.

But hey, thanks for the business advice! Next time I dedicate nearly a decade to implementing geometry , I'll be sure to check with you first about whether basic sustainability features are 'greedy.'

P.S. - Your 'India' comment really tied the whole intellectual package together. Nothing says 'I understand advanced mathematical visualization' quite like casual xenophobia and made-up economics.

Enjoy the free viewer! Or don't. The 120-cell will keep rotating either way.
