Just found these guys, Bompas & Parr, who are Sam Bompas & Harry Parr and are jellymongers - curating jelly events and designing bespoke jelly moulds and other wobbly activities for clients like Habitat, Innocent and the V&A. And they even do glow in the dark jelly. There's not many things I see and really want to do, but this is definitely one of them.
