    ...important in scaling ForecastWatch.com's coverage to over 800 cities. Grabbing web pages is a very I/O bound process, and requesting a single page at a time for roughly 5000 web pages a day would have been prohibitively time-consuming.

Pygame provided all the functions I'd need for image manipulation and display management, and there were a few exi...
