Red cube reflections

A very large red cube (two storeys high) has been installed in the middle of the town square - apparently as a part of a charity fundraising/advert filming initiative by Santander. It was still fenced off and under construction when I passed by but made for a great set of reflections in an unusual place. I'm mildly curious to see what it is all about, and also thinking that it has gazumped the Square which is one of the main prime locations for the Shrewsbury Street Theatre Festival this coming weekend. Will it be attacked by irate fire jugglers on unicycles? If so, I hope I'm there to take the pictures..
