Artistic traffic!

Driving down the M4 in the gloaming just now was exciting, not just because of the close shaves of swerving, jostling traffic, but because of the jewellery-bright patterns it made up and down the darkening curves of the landscape. Crimson necklaces before me, white diamond ones behind: a gem-studded shawl, shimming and twinkling on a rolling conveyor belt over and round the looming hills and dips. Even the spitting rain worked to effect, refracting the beams and flashes and sending them dancing like shards of shattered chandeliers.
Driving home from work on a dreary night can be inspiring!
