A new slant

I occasionally have to leave my diligent students unattended to deal with more pressing matters and today was to check for fire as the alarm went off for the 3rd time.

Confirming it was another false alarm I returned to find that the whole room had somehow shifted and spun through about 30 degrees. My fantastic students had already adapted to the new environment, they are ever so inventive. Sniggering ELF?s that they are?
