Tell the council: Fix my street!
FixMyStreet is another wonderful, simple app from MySociety. Use it to quickly report graffiti, fly-tipping, broken streetlighting, or whatever blights your morning stroll.
All you have to do is enter your postcode, click a map to locate the issue, and even upload photos of your favourite eyesores. I reported a burned out scooter that brightens up my daily commute.
I also had a jolly time looking at posts from other complainers; very satisfying curtain-twitching.
