/* Top X Tips for better ASCII QuickTime Movie Viewing
11) Remember Tom Dowdy, he originally wrote this and is missed by all of us
10) Grow your terminal/console to fit the Movie
9) Ask marketing folks if you can incorporate this code into your latest QuickTime product
and see if they think you're serious, then do it behind their back anyway
8) Set your terminal to White on Black for optimal look
7) Download your favorite movie trailer
6) While you're at it, download some Graphics Importer sample code (why not?)
5) Jedi mind trick your manager "...you want to send me to WWDC"
4) Order the pizza.
3) Dim the lights and turn up the audio
2) Turn off terminal transparancy for fastest performance
1a) Usage [smelltheglove:/Volumes/Spock] moof% ASCIIMoviePlayer sillymovie.mov
1b) Usage C:\ ASCIIMoviePlayer.exe sillymovie.mov
