For mysterious reasons (possibly related to the cancellation of the arm wrestling tournament), Bill and Jon wondered how far they could throw a spare trunnion (a heavy chunk of steel). This led to a contest, and to an impromptu group photo shoot once everyone was gathered outside.
For a little extra fun, I turned multiple similar group photos into animations of the team dancing. (Below the gallery.)

Bill twirls
While experimenting with different techniques

Bill's first toss

Jon winds up

Graceful release
This turned out to be the longest throw

Changing tehnique
Results in somewhat less forward motion

Spectators

Sasha throws

And she tries twirling briefly too

Jamil's toss

Sean has a more side-arm style

John H throws overhand

This is physically impressive, but not the most effective

I prepare myself

Wind up

And launch straight at Cynthia
Against whom I bear no grudges. Please believe me

John R goes next

I like his style
If I ever do this again, I'll try this way

Ed's turn

And release
A very high toss, Ed buried the trunnion deepest in the snow

Last of all, Jeff joins in

SPIDER group photo
Since we were all gathered outside on a gorgeous day

Jump photo
Only one injury sustained (sorry, Barth)

Obligatory Mt Erebus group shot
With almost-obligatory bad lighting, since this always happens at a bad time
