However, I was much more impressed by a product from the German company Woehburk, especially their Cristalline, glass projection screen. I thought that it showed a brighter image than the other products, with better contrast and color. Perhaps I was charmed by the small scale, as I wanted to design some kind of suspended 'chandelier' type array of small glass projection screens. I really like the way that the image is only visible from one side, which makes it appear quite magically, if you're just passing by...

In this video I compare three different Woehburk screens and then compare my favorite with an opaque rear projection sample from 3M's Vicuity range.

Just wanted to post that my current project, A Show of Hands, will be projected this weekend as part of the Dumbo Art Festival. It'll be projected onto the exterior of the old Empire Stores building, overlooking Brooklyn Bridge Park, by the river.  Just near the intersection of Main St & Plymouth St.

Please come by and say hello if you're nearby on Saturday evening! 

I've been meaning to post these videos for months, but just never got round to it...

Late last year, I was immensely flattered when John Reaves, Alyce Dissette and Hal Eagar asked me if I would be interested in collaborating with photographer Janet Sternburg in creating a multimedia exhibit for the Seoul Institute of the Arts.  Of course I said yes, and by January 2009, I was getting deep into design research.

As part of this process I tried to identify a good transparent projection screen.  In the end we didn't go with this kind of projection design, however, without going into too much detail about why, here's some rough video tests I did.  Apologies for the shaky handheld camera (I was in a rush, and working by myself), but hopefully these videos might be a resource for someone else doing similar research.  

This one shows tests with an acrylic screen made by Da-Lite.  I wasn't too impressed with this one... Low contrast, and didn't deal with ambient light very well. This product definitely wasn't going to be good enough to show Janet's photography on...

Here's some photos of another project that I started work on during my DPI residency.  Again, this was made possible with DPI equipment.  The photos were taken by Monica Ruzansky in August 2008, when I was projecting onto a building just off of St Marks Place in the East Village.  These are very early sketches of a project that I will continue to develop over the next year.

I put some documentation online from the Giants projections that I shot at DPI.  You can see it here: www.edpurver.com/giants_light.html

Here's a still from the projections on Dean St last month...  Along with a screenshot of the movie that was playing across all the windows...  I made a quick patch in max so that I could keyframe vertices to keystone the three different projectors beyond their natural capacities.

And I keep forgetting to mention that we're having an informal showing of the video that I've shot at DPI.  It's being projected inside the building at 983-A Dean St this Saturday, 26th July.  It's designed to be viewed from the street.  The building is in the middle of the block between Franklin and Classon (nearest subway C train to Franklin Ave).  

Weather permitting, Monica Ruzansky (www.monicaruzansky.com) will be projecting her beautiful photography on the surrounding architecture and up on the roof, where we'll be hanging out and having drinks with anyone who wants to drop by and join us from 9pm onwards.  Hope to see you there!
