When I first came across this scene, with people sitting on the pavement surrounded by odd household goods, I thought I was witnessing some sort of domestic problem. Turns out, nothing could be farther from the truth. What it is, is the the Ghana community in Bloomsbury who send all manner of stuff back to the needy in their country on a regular basis. Unfortunately, they don't have a website yet.
Don't forget, you can visit Ghana too!
