From the huffington post:

'Robin Hood Tax' Campaign's Hilarious New Ad With Bill Nighy (VIDEO)

A coalition of British organizations calling itself the Robin Hood Tax campaign is proposing a new tax on banks to fund global anti-poverty and anti-climate change initiatives. The idea is to skim about 0.05% off of all speculative banking transactions, which proponents say would raise hundreds of billions of dollars each year and forge "a new deal between banks and society":

"It sounds complicated, but actually it isn't. A tiny tax on bankers has the power to raise hundreds of billions every year - giving a vital boost to the NHS, our schools, and the fight against child poverty - as well as tackling poverty and climate change around the world."

In an ad for the campaign, British actor Bill Nighy, who will star in the next installment of the Harry Potter films, plays a haughty banker who's forced to admit the tax would barely phase the finance industry.

 How can we do this here?

Here is the excellent videocommunicating the concept; please spread the word.
