We recently revamped our Twitter profile and connected it to both our blog and GitHub repos via the awesome IFTTT. Now every new blog post (like this one) and a release of one of our open source libraries gets immediately (well, check-every-15-minutes kind of immediately) tweeted about.
One thing that was missing (or more precisely: my boss thought was missing) was the ability to rotate over a set of images as a Twitter profile banner. And being programmers and stuff we did it (or more precisely: my boss told me to do it). It's called twitter-banner-switcher (I know - awesome name, right?) and is available now in stores near you (or more precisely: on PyPI and GitHub). I should stop with the more precisely stuff, shouldn't I? I should, or more precisely - I will.
Anyway - as always feel free to use, ask, fork, star, report bugs, fix them, suggest enhancements and point out any mistakes.
