Viewer 17-gons

Our Numberphile video about Gauss and the 17-gon was posted this week.

More on the math behind this: http://youtu.be/oYlB5lUGlbw Professor David Eisenbud - director of MSRI - on the amazing 17-gon and it's link to Gauss. See end of this video for a bit MSRI's address at 17 Gauss Way!

Here's David's Heptadecagon:

But equally exciting have been these efforts by Numberphile viewers.

Note these are compass and straight edge constructions. That's the point.

There's an additional video about the math behind the construction.
