Besides a brilliant company name (WDDG is short for World Domination Design Group), the smart execution in the style of WWII government propaganda videos is a load of fun. WDDG didn't take any shortcuts when producing content for each of their site's categories, continuing the vintage slideshow theme throughout. Sure, it's a bit cumbersome when trying to fetch a quick bit of information (a new video cues), and I'm sure SEO presents some challenges - but the site is a fun, playful and simple way to demonstrate their creativity. For an added bonus, view source: they even have fun with code!

Note: had Wddg linked in my favorites long ago, but finally getting around to writing about it now.
