Replying to Post everything lens whacking related

So lately I've been trying this technique called lens whacking. If you have never heard of it then go search it and familiarize yourself. Basically you detach the lens allowing light to hit your sensor at different angles. I have found that it only works with some lenses, for instance, my canon 50mm f/1.8 won't work, evn with the focus set at infinity. But please post any of your attempts or successes using this technique, I would like to see it in action!
