Solution To Barn
By Susan Glass, with lots of help
from Jessica Wong
Acknowledgements: Many thanks to Jessica Wong for the large amount of work she put into
helping construct this puzzle, and to Matt Sakai for testsolving so exhaustively. Also thanks to caller Rob French for
recording the audio sequences. The
checker animations came from Noriko
Takahashi’s web site. The people animations and pictures came from
the Japan
Square Dance Association. The call
descriptions were assembled based on a variety of sites, all of which based
their descriptions on the CALLERLAB
syllabus. Many of the sequences were
based on those found on Vic
Ceder’s web site .
If you’d like more information about Square Dancing, Tech Squares
teaches an amazing Square Dancing course that can count as a PE credit. The
next one starts February 4, 2003.
Pictures of the pturnip team solving this puzzle can be found on the surveillance page.
The answer is LAME
DUCK.
Each dancer represents
a bit of an 8-bit ASCII letter. The
numbers in the ending formation indicate the positions of the bits in a 64-bit
sequence, with each group of 8 bits forming an ASCII letter. When a dancer holds a single BFT, their bit
flips (0 to 1, or 1 to 0). Two BFTs
cancel each other out.
The final answer is as
follows:
|
1-8 |
9-16 |
17-24 |
25-32 |
33-40 |
41-48 |
49-56 |
57-64 |
