Alternator is a multipart font designed for messages, news tickers and banners.        The 'Inverse' variants are the missing lines from the regular and bold versions that can be superimposed to give various two-tone effects.

 

   

Alternator is available as a TrueType font for Mac or PC, and is available either by itself for $8 or as part of the MiniFonts Bundle 2 for $25.
