Is it possible to expose time to the definition?

It would be cool to demo strange-attractor-like systems such as the ones demonstrated in this video. I cloned the project, but I don't know enough GLSL to contribute yet. Could you estimate how difficult it would be to expose a t variable in the get_velocity user-defined function?

There's a frame variable you can use. See https://github.com/anvaka/fieldplay/blob/master/API.md
