I remember being very pleased when I figured out a quick way to draw a ribbon helix! Richardson's diagrams are so much nicer though. Especially the twisted parallel beta sheet (the a-b-a sandwich) on the right hand side of the three images in the middle of the article (glycogen phosphorylase). The orange on one side and yellow on the other is very nice. Oddly, I'm currently looking at some elegantly curved William Morris leaf wallpapers, and somehow they seem similar, lol.
