Petra...concerning "I build them because I need to think. So I sit down with the wood glue, start putting the pieces together and by the time I'm done whatever I needed to think about will be completed. "

I think I'll sit down and play with the glue. My hair needs a makeover, and we ought to be able to do something interesting with the glue. As far as house construction...I prefer to use duct tape to hold together my actual house...
