Seeing the light
Thought the cafe ceiling lights in the Wellcome Foundation offered an abstract on a plate! We were there to see the Smoke and Mirrors exhibition, which looked at the psychology and brain-tricking illusions of conjuring, sleight of hand, misdirection and so forth over the years, from Houdini's escapology and Victorian séance trickery to modern illusionists and openly tricking brain-foolers such as Derren Brown. Nice video clip of Tommy Cooper, too! (Thanks to Ingeborg for hosting the abstract challenge.)
Off to the theatre tonight to see The Play that Goes Wrong.
