From: Xavier Noria [mailto:fxn@hashref.com] 
#    "foobar".gsub(/./) do |c|
#      c.send([:downcase, :upcase][rand(2)])
#    end

cool. also,
irb(main):125:0> "hello".gsub(/./){|c| rand(2)>0 ? c : c.swapcase }
=> "helLo"
or your style,
irb(main):127:0> "hello".gsub(/./){|c| [c,c.swapcase][rand(2)] }
=> "helLO"

lot of c's though, wish i could remove them :)
kind regards -botp
