[plt-scheme] Highlighting parentheses.

I think all your variants are delightful.  Thank you for this burst of  
creativity!

My only reservation is that seeing the whole screen turn to color  
feels like overkill.  Maybe it is possible to color only a few sexps  
*in* (or *out*) from a certain level.  The cursor position would  
determine what is considered innermost, and a configurable parameter  
would specify how many levels to color in one direction or the other.
