So, the first meet of the New Year was on the 9th January, and we all brought our presents along.  I brought a model steam carriage kit, that was an exciting puzzle to solve as the instructions were particularly vague, and Alan brought polymorph to play with.
The polymorph was slightly more successful than the engine which due to some presumed error in construction, does not self-propel.  This is due to the piston being unable to turn the flywheel, itself due to the axle somehow jamming in place.  It still looks moderately elegant.
Next meeting 23rd January 2012.
