“Income redistribution” typically refers to tax-related transfers of wealth — but one mystery millionaire is taking a DIY approach, and it’s actually pretty cool.

The Hidden Cash campaign is just what it sounds like: someone is hiding money all around San Francisco, then tweeting hints about the locations, like a grown-up Easter egg hunt.

Speaking to the Bold Italic, the person behind the Hidden Cash campaign said they were concerned by the wealth inequality in the Bay Area, and though they said they donate to many charities, they wanted to find a more creative way to address the problem.

“I’ve made millions of dollars the last few years, more than I ever imagined, and yet many friends of mine, and people who work for me, cannot afford to buy a modest home in the Bay Area,” the person wrote. “This has caused me quite a bit of reflection. I am determined to give away some of the money I make, and in addition to charity, to do it in fun, creative ways like this.”

The campaign has generated dozens of happy tweets since launching Friday.
