rewind of braid

Here's an interview with him where he talks about it a bit:

Here's his open-source code for implementing a data recording system:

And the article from where the code originated:

thanks, it's very helpful.

I would start by making a deterministic engine, and then applying some variation of the command pattern.

Rewind is simply playing every frame back to the (n-1)th frame, and looping n from max to zero.

I did this for a billiard simulation 20 years ago and it was cool to watch the break in reverse.

As nox_pp points out, this requires a deterministic engine (meaning if you have the same input conditions the same results will occur).
