I was thrilled to be commissioned by Vital Arts, a charity funded to deliver arts programmes at Barts Health NHS Trust, to design signage for the children's daycare ward. The brief: provide a clear message to discourage patients, and their parents, from eating in the waiting room.

I created a band of merry Grub-busters dedicated to policing the area. Nowhere is safe from their beady eyes - they peek around every corner, pop up behind chairs and snoop around reception. The Grub-busters communicate directly to visitors with playful, humorous language.
