Random Movement Generator

[raaed...@gmail.com]

Hey All,

In some games and graphics applications, there is a need to do some random movement in some defined pattern!

Which means you may need to move some object in a random curve, but you need to define the pattern of the curve to oscillate up and down in some speed, for example, that's what I mean by random movement in a defined pattern.

And here's some video to explain the last example: here .

Please note the small fishes’ movement, it moves in a random curve which oscillating in a small speed up and down, and in next levels the oscillating speed increases and creates different curves.

So, my idea is to create a library which contains functions to generate such movement patterns depends on the user needs.

So, Please can anyone tell me if there's anything like this has been done in sympy?
