Bet that took some time

Spotted lots of strips of these pebbles outside one of the buildings on campus - bet they took ages to make. Had a nice long lunchtime walk to set myself up for an afternoon in front of the PC getting my head around Google Fusion Tables.

I've been learning about them via a Google online training package and it was surprisingly easy to follow - whether I'll still say that when it comes to the test stage is another matter!
