Intelligent plastics change shape with light

Intelligent plastics change shape with light - MIT News Office

Wow, how cool. Applications? Mapping wallets that automatically take strike and dip readings under certain lighting conditions? Or something less geeky?... Shoes whose (nice bit o rhyming) laces automatically undo under a certain invisible UV light, thus rendering the unsuspecting freedom fighter shoe less while fleeing... Cars with window blinds that automatically respond to sunlight but not street lights.... Protective packaging for , er, things that shouldn't be expoised to certain wavelengths. like paintings in museums. Arms that automatically slap any inconsiderate flash photographers in the theatre...
thats enough for me.
