Mathematica Programming Challenge 1 Given several points in the plane, connect these points by line segments, resulting in a connected polygonal line that passes through all the points and does not intersect itself. Arrange it so that the line seems to spiral inwards. Mathematica Programming Challenge 2 There are two rhombi, named after Penrose, which you can use to tile the plane. They both have the same edge length; the narrower rhombus has a tip angle of Pi/5, and the wider rhombus has a tip angle of 2Pi/5. Write a program that produces random (whatever that means) tesselations of (part of) the plane, using these two shapes. Will Self
