Mark Lentczner has just (on May 26/28) created a useful/humerous 
graphical diagram of the 100+ operators in the Perl 6 language, 
designed to look like the periodic table of atomic elements.

It's well worth a look:

He announced it to perl6-language[at]perl.org on May 26th, and it was 
announced on Slashdot today.  For those of you not reading either of 
those, enjoy.
