[snip] ObHack: I recently wanted to waterproof my speakers, so's I could use them outdoors. I got a bunch of PVC sheeting and duct tape, and.... Yeah, OK, I'm kidding. ObRealHack: Having built a bass bin some while ago, I needed to move it. No problem to start off with, but a couple of years later the hack comes in actually finding three other people to help me lift it even when they don't know they want to. Cheaper than castors or a fork lift, and more fun. ^^^^^^^^^^^^^^^^^^^^^^^ Or for that matter, know they don't want to!!! -- preferred email address is email@example.com unless otherwise specified web home page URL is http://www.ee.ic.ac.uk/hp/students/ee3/dsm/main.html ...
