There's a small gallery in the park near my house, and this weekend it hosted a showcase of work from new artists and fashion designers who study at the local college.
My favourite exhibit was the interactive Spectrum installation, for which every visitor was invited to contribute by bringing along colourful unwanted items. These things were then arranged in a rainbow of hues on the gallery floor, with the installation growing over the duration of the exhibition.
There was an array of broken toys, packaging, household items, clothing, etc. and all this junk had started looking just beautiful. I forgot to choose something to contribute, so I rummaged through my wallet while I was there and found an old, expired purple loyalty card from a sandwich shop, which I should have recycled ages ago. But hey, now it's art!
