I wasn't suggesting that voting machines use red text on green background. I was suggesting that if radiation is a concern, to use tempest shielded displays. All the ballots I've ever seen were in black and white. I don't see a need for a color display in a voting machine unless you want to display color photos of the candidates. I'm not familiar with what models of tempest shielded displays are currently available, but a black and white model might be less expensive than a color model, or have some other advantage. Of course they probably don't make a black and white tempest shielded display with HDCP. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
