Abstract Thursday - Architectural

Not sure if a rusty old drainpipe fits into the category of architectural, but I'll chance it. I purposely made it diagonal to avoid a bad vertical; the addition of Incy Wincy, however, was purely accidental. I didn't see him until I uploaded onto my laptop....

...which reminds me: for the past four nights there's been a huge spider - well, the size of a 50p piece - in the bath, but by morning there's no sign of him. It's a mystery. Where does he come from/Where does he go???
