Cross Cafe Wall - Prague 7

One day I am going to have time to walk into this cafe rather than just dash past it on my way to a lesson. I am fascinated by the strange sculptures in the garden and on the walls. Clearly someone likes mechanical things. I ask myself, "Why?" whenever I walk past. I don't have an answer. But that's not so strange...there are many questions I don't have answers to! Maybe "because" is enough :)
