Today the weather surprised everybody, Edinburgh basked in 25 degrees - unexpected. We chose to go out in the crazy heat and visited the Camera Obscura and on the way up the five flights of stairs that take you to the original attraction were seduced and confused by the numerous effects and exhibits that guide the way to the top. There are too many to list but I like the sparky stuff (as above), the maze of mirrors and the vortex. "To infinity and beyond" seems the best way to sum it all up. Go see.
