Sledgehammers and other holy things

There seems to be a bit of a theme happening in the conferences I've been at of late - idols. Interestingly in scripture when God is on the move - and wants to mobalise the people he first calls them to smash their idols. I've been thinking about our idols in culture... fame, success, wealth, comfort, beauty - to name a few. What does it mean to smash an idol in todays context? In Minehead it meant taking a sledgehammer to some cans/cabinets that represented various aspects of our idolatry... people were naming their own idols and we smashed them together - figuratively. I couldn't help imagining what it would look like if thousands of Christians actually smashed their idols... TVs flying off balconies and out of houses/alcohol bottles flowing as they come crashing down/computers and ipods??
