It's probably possible to knock it out in a couple dozen lines of PostScript (possibly by abusing the halftone screen mechanism), with your choice of fonts. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

Re: [neonixie-l] eBay: Omni-Ray for sale!
The pattern on the film isn't that difficult to figure out, though printing it in perfect alignment at exactly the right scale might be a challenge. For each "lenslet" (pixel) in the array, there must be 12 possible clear dots in the film, aligned similarly to the bulbs but inverted. For each displayable symbol, the dot corresponding to that bulb's position will be either clear or black. So to light a "0", the dots on the film in the zero position in front of each lenslet must be set appropriately for the shape of the "0". If you're really clever you could even try antialiasing the curved and angled edges of the symbols... Near the top and bottom center of the Message Assembly, should be several pixels with 10 of the 12 possible dots being clear - every symbol but the decimals will light those pixels where they all intersect. Conversely, the upper corners of the film should be solid black since nothing should ever be lit there; judging by the size of the "3" and "4" shown on Dieter's page, none of the symbols should occupy the full width of the top of the screen, nor even extend fully into one upper corner.

The lenses would be hard to re-create, but the film might be doable by laser printing a pattern onto the sort of clear acetate sheets used for transparencies. There would be some geometry and mathematics involved to figure out the pattern to print, but once that was solved, you could make custom symbols. You might even be able to make coloured symbols if you had a way to print transparent coloured ink (or you could use coloured bulbs or LEDs, but with with the right pattern, you could have multicoloured symbols). - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
