February 29 comes only once in four years, so it 
a good day to celebrate by displaying any of the 
following:

a.  A character who is making some kind of 
spectacular leap or jump.

b.  A female character breaking role and chasing 
male character who is normally the forward one 
(as women were given the liberty to do on Feb. 29 
in some countries).

c.  A cel of Touya Kinomoto from CCS, whose 
birthday falls on this day.

I'm going to opt for the last of these, with an 
impressive cel from my collection that shows how 
much dignity the character can muster, even when 
cross-dressed in a school play.
