I decided to imitate chris2's xmas animations and posted a rather large one to ruby-talk (to be fair, I actually used some filler to display the whole AA). If you run it, you'll notice it's also quine-like... The code looks like this: which stands for "happy new year" in Japanese. For the sake of symmetry, I also made the following The carrier, with base64-encoded text arranged to form some ASCII art, is based on Christian's original one, with a twist to:

• remove all the prefix code
• feed the encoded ehhmm code (i.e. the sources as found in the message, minus the trailing decoder) to the lambda resulting from evaluating that code

It basically works like

"LENGTH base 64 text
 here, whose spaces will be removed before unpacking;
 Essentially, something like:
 lambda do |myself|
   ... do something with my own sources ...
 end".
instance_eval do |x|
   y = x.gsub(/ \\n/, "")
   eval(y[5,y[0,5].to_i].unpack("m*")[0]).call(x)
end

Few people ever use that, but instance_eval passes self to the block; it is thanks to this that I can move all the code to the bottom, leaving a mere quotation mark as the prefix, so it barely disturbs the ASCII art.
