Not sure what you intend for “real time motion graphics” though what the guy does do is plain and simple art with nothing at all being simple about it.
Cool stuff, some of it may even be procedurally generated in whole or in part.
It’s not impossible to reproduce using any engine that has any Flow Dynamics or Particle Dynamics
This is an OK physX example using the free unreal projecthttps://youtube.com/watch?v=5nsD88vqNbI
This is an applied example of using the same phisX stuff in a slightly more destructive fashion
here is an how to - for getting Flex (physX) to integratehttps://youtube.com/watch?v=IEnVWCOQ8eU
If like the guy all you are interested in is producing an end result and filming it, you can build the engine and go through the trouble to do it all. If you are making a game, I don’t recommend it, since it’s unlikely the game would work on non Nvidia platforms.
Though i’m sure the ATI group has it’s own version of this.
