It's my first post in this area and this barely validates as a "showcase case", but: I've finally managed to update my own Web presence, resulting in flamingruby.com. It's primarily a blog, but some of my projects are on display there too. This site has actually been up for months already -- wasn't going to post it here, but thought it'd be nice to prove that I've actually built something with PW after all.. Being responsive is fairly standard stuff these days. In this case no frameworks were involved, though; it's all hand-made, built from mobile first perspective and based on content alone, instead of predefined breakpoints. Some details I'm still not happy about, so it'll probably get tweaked every now and then, but at the moment things are pretty much in a stable state. Since it's a personal project, I've been slowly adding small tricks here and there, none of which really count as anything "special." One addition made just today, mostly as a proof-of-concept, is a combination of a simple module and new subdomain (static.flamingruby.com) to automatically serve assets from (at least in theory) cookie-free location. This is described in more detail here. For home page I built an importer module (with AngularJS GUI, which was actually quite fun) that periodically pulls content from various feeds.. a bit like what Nico did with his social timeline, but nowhere as cool as that. At the moment content is being pulled from GitHub (for which I had to put together MarkupLoadAtom) and Twitter (which kindly killed it's RSS support just in time, so I'm using rssitfor.me instead.. although that site interestingly spits out Atom and not RSS like one would expect.) That's just about it.
