Interpolating (and extrapolating) 3D turtle programs in Beetle Blocks

Turtle programs can be treated as objects to manipulate. In this demo a program takes two turtle programs as input and creates a new program that is the interpolation between the input programs. An input of .25, for example, will behave like one-fourth of the first program and three-fourths of the second. An input greater than 1 will extrapolate beyond the second program in the direction from the first program. This idea was explored in (Kahn 2007) for two-dimensional turtle programs. Here we generalise it for Beetle Blocks (Romagosa et al 2016), a 3D version of Snap! (Harvey and Mönig 2010).
