Could a garment be created with a pattern in ultraviolet? It would appear white, but if you shone a UV light on it the pattern would come out. Many apparently white flowers turn out to have patterns visible in UV, which bees etc can perceive.

Seems like there'd be a certain market for fashion like that, with a sort of "hidden meaning."

I was sitting on my porch just now and this fresh breeze came through, lifting my mood immensely. I looked up and sniffed, and the air was so fresh and beautiful, it reminded me of something long ago that I loved. I got more focused, smelled the air, identified the components; and it was a sea-breeze. My porch is 250mi from the nearest coast, but the breeze was unmistakeably a sea-air, carrying the salt and fish and general smell of the sea; specifically the south Atlantic, and the website [1] shows a swirl at 10kft that could indeed have lofted me a sea-breeze up from Myrtle Beach where my family used to vacation.

I request that HackerNews build me an app that will display where the air mass over my current location originated. Take this [1], and run it backward.

Can it be done?
