I have to add one more item to the up-side-down/right-side-up quiz Ed Winkleman had on his blog a couple weeks ago. I posted a photo of Bill Brand's Masstransiscope over on my Creative Time blog. Mr. Brand commented and kindly pointed out that fact that the photo of his piece was upside down and backwards. My bad. I've corrected the orientation on the CT blog. You can click here to see which one of these is right.
