PROJECTS

3D Printing & Geometric Models
==============================
	Print run late Thursday; depowdering and analaysis
	daVinci models in Mma
		Tetrahedron finished
		Octahedron next; needs more systematizing
	Kepler punch bowl 

D-Forms
=======
	Ribbon curves question
	Hypothesis (Stephanie):
		Any ribbon whose edge realizes a smooth plane curve
		which is not a straight segment
		must be orthogonal to the plane of the curve
		at every point of the curve.
	Even two circular arcs connected by a straight segment is not C^2:
		acceleration plummets to zero.

Pop-Up Books
============
	Rotary animation, V-fold rotation on back face, Mma animation
		Working, almost finished
		New templates needed
		New card model(?); photo
	POV-ray animation of V-fold on platform underside
		Import computations from back-face rotation
	Examples of how to use rotary motion in a card:
		Cow jumping over moon?
		Oppositely rotating spiral eyes?
		
Protein Folding
===============
	Models complete
	Bond angle info, links on Web page?

Interlocked Chains
==================
	Photos of 11/2-chain: done; need high-quality JPEG
	60-deg (equilateral triangle) weaving, braced. 
		Quite unclear if locked.  Need a better model.
	K'nex-like mechanism at angles between 60-90
