It definitely addresses their target audience. They're a web design firm that claims it has a reputation for designing "flexible websites that look fabulous on every type of device." Being a design firm, their use of eye candy works for potential clients who may not be too technical, yet realize there's this need for "making my web look good on my phone and computer" (as one former client once said to me). And it's pretty nifty eye candy too. It's the first time I've seen someone change an illustration based on a viewport size. Not groundbreaking, but a pretty neat idea. Oh, and to address your question about who would ever resize their browser to see this - only developers would do that. These could be developers working for their potential clients, which means this eye candy can be a good conversion tool. End users wouldn't resize browsers like this, of course. An end user would see just one of the illustrations, depending on which device they used. On an iPhone, they get the thinnest illustration. On an iPad and some laptop browser windows, they get the middle illustration. On large screens, they get the largest illustration.
