Architect perhaps...

Good old wooden blocks. The majority of these my Dad made back in the 70's. They would have been off cuts from furniture making.
They have worn smooth over the years of constant play. Now, all these years later, they are getting played with again. But instead of the cars we tried to make, the wee Fella comes up with the most amazing creations... 'Piggie Houses' he sometimes calls them.

I like how this one is perfectly proportioned for Papa Smurf.
The best bit about this architectural delight is the piece beside Papa Smurf, the yellow screwdriver handle that has been pushed into the blue circle. The wee fella rushes in on Sunday with this creation in hand and says..
"Look Papa, I've made a tampa!" ... stay tuned for the portafilter and coffee machine that will no doubt either be created, or aquired...
