text: Elvis knows this is an obsession of mine ; in Sunday 's Chicago Sun-Times I published a long article that questions widespread beliefs about the Texas Instruments digital projection system and extols a much cheaper film projection system called MaxiVision48 , which uses existing , proven technology , and produces a picture its patent holders claim is 500 percent better ( not a misprint ) than existing film or digital projection , take your choice .
