Here's a small, recent example of the drip castles I like to make at the shore. They are usually much larger, and attract small crowds of kids who help out. Many observers say they resemble Gaudi's work.
I have been building them since I was a kid. They don't last quite as long as most software. It would be fun to try to mix up some plaster or something and make a longer-lasting castle.
Where did this design come from? Perhaps from the south shore of Long Island, where my father grew up? I have rarely seen the style attempted.
I should make an MPEG of a time lapse movie I made of the construction and eventual destruction of one of these.
