The 'Ivy' by Sono Mocci from Italy was recently shortlisted in the Seoul Cycle Design Competition 2010, a contest designed to help the city of Seoul develop a healthier cycling culture. How much better-looking is this lock than hard chain metal?
As the designer says:
Why does our bicycle need to be connected to light poles by chains like a criminal in prison? Inspired by nature, the design of this cable wire lock is a mimicry of ivy. It is unified in our daily scene and promotes protection of the environment. It is soft and feels natural. 'Ivy' is a plug to awaken the relationship between you and society. 4 dial number lock, steel wire + silicon gom covered. 2 sizes: short (900mm), long (1500mm).

I agree. The bike thieves in my neighborhood would laugh at this lock. It's pretty, but I think I'm going to keep using my Kryptonite Fahgettaboudit lock plus cable to secure the other wheel.
Looks easy to cut through.
does not look sturdy enough for me- but maybe could be used to secure panniers to your bike. Bike thieves aren't looking to take those, and would prevent crimes of opportunity (snatching your helmets and bags)
agreed. I wouldn't use this as a principle lock for my bike. style defunct function on this one. pass.
