Assuming it's not actually raining, we're planning on going to the Cody Dock, Cody Wilds launch party on Sunday. https://www.facebook.com/events/805976122778470/
with a short detour to Trinity Buoy Wharf to see the Long Player http://longplayer.org/visit/.

For all the peeps in East London, if you've got nothing better to do this Sunday afternoon, you might like it. Especially if you bicycle, you need to get yourself to Twelvetrees Crescent and then walk/cycle down the East side of the Lea and Bow Creek. Bromley-By-Bow is close, or come at it from the other side via Star Lane DLR. https://www.google.co.uk/maps/@51.5237749,-0.0079912,18z/data=!5m1!1e3

Of course, if it's raining all day, then maybe not.
