University of Iowa Farm Machine Music This is just amazing - a work of genius! Click on either image to view the video. This incredible video has been passed around the Internet as a real-life contraption. The myth is repeated widely; indeed, I received it in an e-mail from a friend that believed it to be real. The first thing I did was look at the University of Iowa website for the named music and engineering schools, and of course they did not exist. Here is the text that goes with the video clip: "This incredible machine was built as a collaborative effort between the Robert M. Trammell Music Conservatory and the Sharon Wick School of Engineering at the University of Iowa. Amazingly, 97% of the machines components came from John Deere Industries and Irrigation Equipment of Bancroft Iowa, yes farm equipment! It took the team a combined 13,029 hours of set-up, alignment, calibration, and tuning before filming this video but as you can see it was WELL worth the effort. It is now on display in the Matthew Gerhard Alumni Hall at the University and is already slated to be donated to the Smithsonian." The real source of the video is the Animusic company.

| Digital Phosphor Technology (DPX) (video link below) This is NOT a paid advertisement for Tektronix, but after reading about this new technology in an article in RF Design magazine and then visiting the Tektronix website, I felt a duty to bring it to your attention. 
Shown above is a couple screen captures of one of the videos available on the Tektronix website. It pits an Agilent E4440A PSA against the Tektronix RSA6100 RSA with Digital Phosphor Technology (DPX). The signal is a signal that is experiencing an infrequent frequency hop due to a faulty PLO. The DPX display not only captures more information in less time, but it uses color coding to imply the relative length of time a signal dwells at a particular frequency. Hotter colors (more duration) are redder, and cooler colors (less duration) are bluer.
