Stripy

Saw this piece of installation art on the entry to baggage collection, had to blip it really. In real life the blank & white poles that sit in front interfere with the stripy background, playing havoc with the eyes. Think it is probably multi-slit diffraction (hopefully Mrs Harrow would be proud!)

BTW Guv & BG, would text but too late, have arrived OK, weather pleasant (55 ish and sunny)
