Some ways to reduce flicker:

1. Reduce light/dark contrast between displayed colors by adjusting
   colors and/or monitor.  Try colors with similar luminance but
   different hues.

2. Use a font designed for interlace.  There are some floating around.
   (on this net I believe)

3. If you are writing interlace software, avoid thin horizontal
   contrasting lines.

4. Sony analog RGB monitors like the KV1311CR seem to have slightly
   longer persistence than ours.  If you can find one, they're nice.
   Analog, digital, composite AND it's a TV.   $500

5. If you want to spend MORE bucks, get a REAL high persistence
   monitor, try Electrohome ECM1301 HR Color, or Mitsubishi
   C-3479LPAG-WC.

6. Wear sunglasses.
