The image is of Lego Duplo blocks we use modelling software layers. This particular day we compared a software model we had talked about a couple of years ago that we had modelled with how we now see it. Theres nothing quite like the tactile feel building with lego blocks. If you look carefully you can see the labels representing layers in the design.
