Bill commented on the availability of the Beam Brush device at SELEM 2010...
Basically, the problem is that Bill has hundreds of ideas, but there are only so many hours in the day. At the time of his presentation at SELEM (back in August of 2010), he had something like 13 *major* projects in the works.
Some of those projects included Quickshow 2.0 for the FB3, the Beyond 3D engine for the QM-2000, the Beam Brush device, the Pangolin Show Site, Quickshow for the QM-2000, an improved LivePro interface, a new design for a Pangolin-branded scanner set, and several others that I can't remember off the top of my head.
Bill also realized at the time that there was no way he could finish all those projects by the end of the year. In fact, he was beginning to understand that by trying to juggle so many different projects all at once, he was actually slowing himself down. So his plan was to pick *ONE* project and see it through to completion before he did anything else. And his choice was to work on Quickshow 2.0, which as most people know, is now available.
As for the Beam Brush device, it's been in development for several years, and it's gone through several revisions. It started out as something about as large as a coffee cup. Then it was shrunk to the size of a soda can. Now it's down to the size of a roll of quarters, and it's amazingly fast.
Bill said he's measured something like 70 newtons of force on the moving section of the device. It's so fast that it will end up having "size" information fed to it at roughly the same speed that point data is fed to the scanners and color data is fed to the lasers. Think about that for a minute...
So yeah, it's not available just yet, and it might be a while yet before it's released. But Bill is certainly still tweaking the design while he waits for the production arrangements to be worked out. When it does come out, I'm sure it will exceed everyone's expectations.
But in the mean time, we need to be patient. Pangolin is still a small company with just a handful of employees, so they can't do everything. (Much as we might want them to.) Personally, I think Bill is smart to focus on one thing at a time. After all, he still has a company to run...
Besides, if you had to pick something to be finished this year, I think a lot of people would choose Quickshow 2.0 over the beam brush device anyway.
