This is the folding of a cat originally folded by J. Anibal Voyer Iniesta. I folded it in about 30 minutes with a single piece of square paper originating from an A4 sized sheet of paper. I couldn’t quite get the face properly though.
Origami is quite relaxing actually — it helps to keep the hand and the mind busy on a single task, which comes to think about it, is quite a lot like meditation. After the folding you get a sense of achievement of creating something that looks like nothing of the original.
