Interactive interpolation visualisation tool

Here's a nice tool for visualising bezier curves, and how they're made.
This was really helpful when coding up my own lerp (linear interpolation) python library and writing a recursive bezier function.

Here's the main lerp algorithm in a python function to start you off:

def lerp(input1, input2, step):
    """ Linearly interpolation between input1 and input2 given
    a value between 0.0 and 1.0.
        input1 (int): starting integer to lerp from.
        input2 (int): destination integer to lerp towards.
        step (float): float value between 0.0 and 1.0
    return (1 - step) * input1 + step * input2
