Necklace Graphics Upgrades

This past week, I've been concerning my game-programming time (what little there has been) with doing a graphics overhaul on necklace.At present, I've got some shadowing and some refraction, which makes things a bit nicer looking.Next up, particles to indicate desired tangency (instead of those ugly pink lines).
If I continue at this pace, expect a graphically-updated release of necklace around the end of next week.
If you've played the current version of necklace, you'll notice that the level structure has changed significantly.This is because I'm moving to authored, rather than generated, levels.These are more satisfying to me -- though I'm not ruling out bringing back generated levels at some point.
