All of the rainbow

This photo was created by taking an unusual glass (see extra), giving it a good clean, putting it on something black, shining a strong light on it and snapping. M found the glass in the street. Can you imagine anyone chucking it out? Its surface is covered in tiny square pyramids and lustre. The facets of the pyramids glitter and gleam with the lustre's rainbow colours.

The glass is now happily repurposed chez nous. Note the sad face pariedolia.

Thanks for always hosting the abstract Thursday challenge, Ingeborg.
