Demo: 3D railway in 256 bytes of code [video]

I've downloaded/tried this demo before, but the cheering in the live video makes it even better. Is there more video of this convention?

Edit: Found another longer video https://www.youtube.com/watch?v=fATsm_k_d0I

The demo immediately preceding was even more impressive to me: https://youtu.be/fATsm_k_d0I?t=658
