I've always been fond of origami, and in some periods I also had time to fold some as a hobby. Alas, this is not the case any more... most of the times.

I'm also proud to produce my greeting cards for birthdays and occasions, when I remember to actually make one (which happens seldom... but happens). Some time ago I stumbled upon a neat design for an origami envelope - although I don't remember where I saw it, I've found a couple of web sites that include it (e.g. here). So... two of "my" things coming together...

Then I'm fond of Perl, of course. So why not kicking it in and use it to add an image to the back of the envelope... automatically?
