Rotation

Here's the idea.

Take a self-portrait and divide it into a 6 x 4 grid of square 'pieces'.
Now randomly decide whether each piece is rotated through 0, 90, 180 or 270 degrees. Decide this by tossing two coins one after the other.

Heads Heads = 0 degrees
Tails Tails = 90 degrees
Tails Heads = 180 degrees
Heads Tails = 270 degrees

And doing this 24 times gave the following sequence -

HH TT TH TT
TH HT TH TT
HH TH HT TH
HH TH HT TT
TT TH HH TT
HH TT HT HH

Re-assemble the grid and swing "your arms in a wild rotation"
