I have no relationship with the company at all, but I found this on kickstarter & it looks like it could be a great fender for some commuters who don't want one on the bike full time:

BTW, kickstarter has had a ton of bike-related products lately. Some of them are pretty cool (I was in on a bike iphone mount that didn't make funding, but was super cool.) while others seem pretty out there, but it's nice to see people looking at the bike space to create innovative products.
