Color Wheels
Remember a while back we were joking about how big the color wheel converter would have to be for a big screen TV?
Well take a look at this!: http://cgi.ebay.com/ws/eBayISAPI.dll...&category=3638 |

I guess if you want to be a big wheel in the television business you get one of these Good argument against the CBS sequential color system. I have this book and it's filled with all kinds of great large format historical pictures. Published in 1991.

We do appreciate these gems. Here's the picture someone was too lazy to post.
Check out the industrial motor from a sawmill. |

Ignoring the issue of the huge mechanical color wheel (they could have built say a loop of colored RGB film that traveled up the CRT screen, over the top of the set, down the back, then under the set to come back in front of the CRT), the motion artifacts of this color system look quite bad. Any moving object will leave a trail of red, green, blue, etc fringes. Thankfully, they dumped this idea for a broadcast standard.

All of this reminds me of an article I recently saw in the papers. It was about a image projector that could make an image appear in thin air right above itself. Supposedly sucked in ambient air and "treats it" in some manner and then shoots it back out the top (like a toaster).
Don't know exactly who what why or where, but sounds like it may have a scanning disk inside. Dunno, but what's old is always new again. Anthony |

Anthony,
I'm sure that disc you discribe is for medicinal purposes only. |

Eh? Whatchoo mean?
The article was for real, and the wild thing is that the projected display was interactive...........if it was displaying a button you could actually push it to activate whatever it was supposed to do. This thing is so Star War/Trek that if it's feasible in the real world it'll be a huge breakthrough. Anthony |
