Rectangles

This afternoon I went up to Newtown proper in search of a photo I could say was about shapes. The first thing that was evident was a sea of rainbows, in prep for Sydney WorldPride commencing tomorrow and continuing until 5 March. Newtown has long been a catchment for a diverse population which is just one of its attractions. Then I saw a sea of rectangles, snapped it and now I'm blipping it. 

Thanks for hosting another interesting abstract challenge Ingeborg.
