I am taking a collage level physics lab right now, and we just did a lab on RC circuits; I thought it was cool to learn how the RC circuits could be used as high-pass or low-pass filter for a speaker(It was cool to remember seeing an RC circuit in the sub woofer I had installed in my car years ago(but did not know what it was at the time). I was like wow. I know how that works now :) ). Any ways I would suggest looking at what is being done in some university physics labs and 'borrow' there good ideas. yea a lot the labs are kinda boring but there are some good ones.

I believe that its illegal to let a crawlers run 'wild' on the internet in the first place(unless you have permission to do so). at least that was what i was told in my cs class where we made a web crawler. So in either case they will catch a 'bad' guy... but seriously I don't think this is fair. If i hack my friend's computer and install a VNC program on it and use VNC to use there computer to go to the 'porn' site. then they get there house searched! it seems too easy to 'fuck' with this and frame some one???
