Was first sent to me as a joke... but I now use this at least 3x per week. Hilarious, really. I do recommend trying it out if you're trying to flow as there's some real science behind background noise and it's ability to help focus.

I love this. Unfortunately it was shared a while back here by Adam Kazwell: http://www.producthunt.co/posts/72 We need better dupe checking and search but going to hide this for now. Sorry, Annie! Btw, check out Nois (http://www.noisli.com/), previously posted here: http://www.producthunt.co/posts/110
