Just saw this on Kickstarter. Kickstarter is an awesome website designed to help people raise money for start-up inventions, projects, products, films... People basically submit an idea and set a funding goal. Their project will only get funded when they reach their goal.
This particular project set a funding goal of $37,500.00 which is a lot for Kickstarter and crushed it. So far the TiGr Titanium bike lock has raised over $50K and it looks like if these guys can pull this off we'll be seeing these on the streets soon. Check out their Kickstarter page for more info.
"The TiGr system includes a flexible Titanium bow and a compact, highly pick resistant lock cylinder. The TiGr bow has a protective coating to protect your bike and stores snugly and unobtrusively on the top tube with simple and light weight straps. The Titanium bow is flexible so you can lock your bike to a variety of structures up to about 5 1/2” in diameter. Depending on your wheel base, rim and tire configuration, you can even lock both wheels (without removal) and frame to a structure."
