Years ago, somebody told me that the eye responds more if the available
energy is clumped into bursts.  This was during a discussion of
multiplexing LEDs (or LED decoders).  The idea was that multiplexing
LEDs actually increased the apparent brightness for a given average
current.

I looked around, but didn't find anything to confirm this.  Has anybody
seen any charts eye response vs duty cycle?  Any suggestions as to
where I should look?
