Together we POP! (read description)
My first thought on POP was to make it exciting with a hint of mysterious shapes and element.
I think these colours will bring people together and to imagine this art being display in a public street. It will sure bring various people from all walks of life to stop for a moment to ponder on this burst of colours. However, the true POP burst of colours will be the diverse people stopping by together making their own interpretation on their and that's the beauty of POP.
