On 'popsicle stick bombs', longsword dancing, and (stellated) polygons!

 

Here is a link to slides on this fascinating topic that we'll explore today!

And here are the two short films on the geometry of longsword locks:
Steel Phoenix
George Hart's Simons Foundation film

Here's a link to a 1930s film of rapper sword dance -- very cool!

Here are snippets from a 2025 rapper sword competition, with lots of different groups and styles.

And here's a contemporary group filmed in 2012: amazing moves

(I highly recommend getting involved with a rapper sword, longsword and/or Morris dance group, as a dancer or musician!! ;P)
