I just came back from the CES show, last week. I saw that display. It wasn't doing that routine though. Only a portion of it was being flipping between some test patterns. I guess they were tweeking it.

In the spirit of this group, a large array of NE-2 bulbs would be a neat project. I've already used opto-triacs on my big clock; they should work nicely for a multiplexed display.
If anyone is interested in sharing the effort to develop a 2-board solution (1 board roughly 8" x 10" for the bulbs, the other for the AC supply) then send me a private message.
It would be roughly a 10x24 matrix of bulbs for each board, and I'm guessing a 4:1 multiplex rate would work.
The AC supply would generate a roughly +/- 170V square-wave, around 250Hz, and would need to operate from 110-240VAC, 50/60Hz
Control would be from readily-available FPGA boards on Ebay.

I've seen NE2's available from China for a decent price when purchased in-bulk.

Gregebert, do you have anything on the web on your neon clocks?

No, I dont, partly because I dont have time to provide design-support or PCBs. Only what I post here.
After seeing the stunning steampunk nixie clock pics from Mr. Parry, I'm almost ashamed to post pictures of my clocks...

I really like how LOUD it gets when displaying greyscale.
