DSoTR - Did this with Mark Pesce, Mark Jeffrey, Josh Crandall and others.
Weird Entertainment Suggestion - Dark Side of the Rainbow, or DSoTR - Yes, it’s worth doing! A number of years ago I foisted this on our Digital Dinner group. We all had some cocktails, cued up Pink Floyd’s Dark Side of the Moon (DSoTM) CD and started it in synch with The Wizard of Oz. What you do is “watch” the movie but “listen” to Dark Side of the Moon, so Pink Floyd becomes the soundtrack. Mark Pesce, Mark Jeffrey, Josh Crandall and a number of other cyber celebrities did this with me years ago. We all loved it.
Below is one of many websites dedicated to this phenomenon. Click on set-up and don’t read too much beyond how to do it so you don’t ruin it. The quick instructions go like this: queu up Dark Side of the Moon in your CD player by hitting play and then pause immediately. Then, start the Wizard of OZ in your DVD player. Right before the actual movie starts that cool old lion roars three times. Right after the third roar you hit play on the CD player and switch the sound so you’re now listening to Dark Side of the Moon. (We chose the third roar, although some people argue fine points about when to actually hit start.) Sit back, and enjoy the way your brain creates meaning and connection. It really is great. I also believe that this phenomenon is similar to harmonics, or the self similarity of the Universe.
To recap: Yes, I have done it. Yes, you should try it. Yes, if you want to make it a party, that would be a good idea!
