Fractal portal VFX idea

A while ago I was watching Chris Danforth's lecture series on chaos. During one of the lectures he showed the Julia sets, which you can play around with here.

I thought that moving along the negative real axis would make a really cool portal opening effect. I made it a thing, enjoy:

This was done in Unity. The portal effect was made using a shader. Making it so that the guy walks out the portal at the right time (or any time that wasn't immediately or teleporting back and forth) was a pain. The glow effect was another area that was a bit rocky. Apart from that, not too bad.

Please take or adapt this idea, I would love to see it done well.

Until we meet again 👋
