METAMORPHOSIS REVEALED

From the study Metamorphosis revealed: time-lapse three dimensional imaging inside a living chrysalis, by Tristan Lowe, Russell J. Garwood, Thomas J. Simonsen, Robert S. Bradley, Philip J. Withers, published 15 May 2013 by The Royal Society:

"Studies of model insects have greatly increased our understanding of animal development. Yet, they are limited in scope to this small pool of model species: a small number of representatives for a hyperdiverse group with highly varied developmental processes. One factor behind this narrow scope is the challenging nature of traditional methods of study, such as histology and dissection, which can preclude quantitative analysis and do not allow the development of a single individual to be followed. Here, we use high-resolution X-ray computed tomography (CT) to overcome these issues, and three-dimensionally image numerous lepidopteran pupae throughout their development. The resulting models are presented in the electronic supplementary material, as are figures and videos, documenting a single individual throughout development. [...] In the future, this form of time-lapse CT-scanning could allow faster and more detailed developmental studies on a wider range of taxa than is presently possible."

Austin Osman Spare

Austin Osman Spare (30 December 1886 – 15 May 1956) was an English artist who developed idiosyncratic magical techniques including automatic writing, automatic drawing and sigilization based on his theories of the relationship between the conscious and unconscious self. His artistic work is characterized by skilled draughtsmanship exhibiting a mastery of the use of the line, and often employs monstrous or fantastic magical and sexual imagery. (Wikipedia)

Artificial Hearts

Oritsunagumono

Oritsunagumono ("things folded and connected") by Takayuki Hori.  The artist printed images of animal skeletons and discarded trash onto translucent sheets of paper, and then folded them into origami animal shapes. Hori folds each animal -- both bones and trash -- out of one uncut sheet of paper. (via Fast Co. and Colossal)
