What do consumers like? Games. And engaging them with a custom game is a great way to brand your business.
Flickr Memari (beta) is a nice little site that lets you create a memory game by mining your Flickr images. It's pretty simple, you provide your Flickr login info and the "set" name of your chosen public Flickr gallery (at least 18 images) and you get a quick matching memory game in return. Once you have the game, you can copy a URL, then send it out to your friends so they can play your game.
You could also use this to engage customers. Set up a public Flickr gallery with product images, people from your company and so on. Then your sudtomers will enjoy playing a quick game will your brand image is impressed upon them.
Unfortunately, the URL is long, but with a little tweaking you could create a custom link to the game. What would make this even more useful would be an embeddable widget for you blog, website or social profile. This site is still pretty new, so hopefully something of that nature is in the works. We'll keep checking.
