Strandbeest are an invention by Dutch artist Theo Jansen. The “creatures” are designed to live on their own on beaches in the Netherlands, taking power only from the wind. They are constructed almost entirely from yellow plastic tubes and scrap materials. Some Strandbeest are even able to detect when they are entering the sea, and switch direction to go back up the beach.
I saw a Strandbeest model on eBay and couldn’t resist buying it and building one. Below are some pictures and videos from the assembly process.
