A filament bulb isn't going to be *that* fast because of thermal
inertia. Moderately crude PWM would do. If you want fast and
fancy you'd have to use LEDs (no bad thing - another project for
you)

I have the print article (a very comprehensive 10 pages), showing
how to make the various "bulbs" etc, which I can scan
