You all know Buckaroo Banzai, don't you? Among other things, he was a physicist, neurosurgeon and a rock singer fronting the band the Hong Kong Cavaliers.
Doug Drexler may be the closest thing the world of Star Trek has to Buckaroo Banzai. He started out as a special effects makeup artist (winning an Oscar for his work on the underrated Dick Tracy), moved into graphic design illustration, and then into CGI visual effects.
He has one of the coolest blogs around, Drex Files, wherein he shares the wealth of material on the projects he's worked on, with special emphasis on Star Trek and Battlestar Galactica.
And now he's got another installment of Drex TV, his video blog look at the stuff we fans love. Check it out: http://drexfiles.wordpress.com/2011/04/14/drextv-04-temporal-sonar/
