Reading an article on Polygon, I clicked on some white space on the site, which turned out to be a catchment area for an advert far above. Grrrrr, I said, shaking my fists at the sky. But before I could add them to my hidden click shitlist with PC Gamer and NetworkN, I was rather taken with what had appeared. Not a big, flashing advert, but rather a game to play. A game – Contre Jour – that it turns out is really rather lovely. Advertising, folks – it works!
