In addition to Pong, the grid contra I've tried at two dance weekends, there's also some six face six dances I wrote; only "two out of three ain't bad" has actually been field tested. I've had it succeed and be enjoyed, I've also had it degenerate into a circle mixer.

Hi Seth,

Ages ago you mentioned your dance Transgressions on SW and I made
some snapshots of it.

I checked  callers box and notice that the link to the snapshots
in the caller's notes of
  http://www.ibiblio.org/contradance/thecallersbox/dance.php?id=12040
is no longer valid as picasaweb is dead.

I've moved the snap shots here:

so you can send an update to Chris to fix the callers box listing.

I've also added a few more snapshots of the paths and neighbors met.

Luke Donforth wrote a very interesting grid contra which he called Pong.
It has both progression and transgression which changes during the dance.

The paths of couples are diagonal but bounce off the boundary of the grid,
thus solving the problem of some couples not moving very much or at all.
However this was at the expense of have 'changing states' that dancers had to be
aware of.

I had corresponded quite a bit about it. He actually tried the dance at one point.

I've attached some comments about it and this is video about the math
