I haven't done Highdeas in a long time because there has been, over the past year, serious curbage. BUT:
On Saturday I met up with my friend and we saw Hot Fuzz and I got two Highdeas right before we saw Hot Fuzz:
1. The 'Make Al Gore Happy' Light-switch Plate!
This is a light-switch plate with a picture of Al Gore on it. When the light is on, Al Gore's face is angry. When you turn the light off, Al Gore's face brightens up into a glow-in-the-dark smile. Parents could tell their children "Don't forget to make Al Gore happy!" to remind them to turn off lights. If every family had just one of these light-switch plates installed in their home, there would be no more global warming at all.*
2. The "Blockberry"
This is a quarter-sized pocket device that renders all Blackberries (or equally annoying devices) unusable within a, say, three foot radius of the user's body. Regular normal people with social skills could use it when they see their unfortunate tech-addiction-stricken brethren, and Blackberry addicts could employ it at dinners and on vacations as a sort of digital antabuse. (I know this one is sort of obvious, but we need it!)
* This is a "Highstatistic"
