As seen through my new macro lens, this is the test (calcium carbonate structural shell) of a small sea urchin that was unknown to science until one was purchased on eBay in 2006 and subesqently described by Natural History Museum scientists Simon Coppard and Heinke Schultz. I bought this test on eBay right around that time, unaware of this fact.

Sea urchins are members of the phylum Echinodermata, which also includes sea stars, sea cucumbers, brittle stars, and crinoids. Like other echinoderms they have fivefold symmetry (called pentamerism) and a mouth locatted ventrally. This species is from New Caledonia, and this particular test is about 1.6cm wide.
Ok here's what happened. I simply asked Kim to hold the light while I was making to focus. And well... this happened ;)

Experimenting with my old lenses on a new camera to see what happens. This is one of 2 test shots. The first was taken with an ancient silver version of the Helios 40. This is a modern Zeiss lens (also 85mm).
Welcome to Planet Frost
Our tour continues...
As a center of science and industry, Planet Frost is at the forefront of cutting edge research and development. It is not unusual to see experimental rovers like this one being tested, zipping about on the moondust flats.
This one is built on a 2009 RC chassis (bb0396c01). I saw one on bricklink for a few bucks so I thought why not? It is a bit underpowered (only 4.5v) but fun anyway.

Trying out a Sigma 150-600 in the photographic shop... this was in the window over the way. Impressive lens, but boy is it heavy.
First you must plant the seed, then you must wait for it to grow into something beautiful.
This is not a finished product but merely a weight test for the legs of a current WIP mech. While waiting for parts I was tearing down this old beast

and because the top part is made of mostly plates I thought it would be a good weight test for the new legs. The result was this strange looking thing.
Passed the weight test no problem, which is surprising because the six legs it had before were prone to buckling out under the weight.
Also, I edited the photo a bit to try to make the black blend better with dark bluish gray. It took away some detail but this is just a WIP thing anyway.

The lens is designed for 16mm motion-picture projectors with a 7,5Ñ…10,4 frame size.
Electro-Motive Division, along with Union Pacific, did some high-altitude testing of EMD’s SD90MAC-Hs at aptly-named Plainview, Colorado, in February 1998. Here, UP Nos. 8503, 8502 and 8505, along with specially-painted EMD No. 8504, splice the EMD test car at Plain siding on Union Pacific’s Moffat Tunnel Subdivision.
The newest addition to the ground of the Pima Air and Space Museum in Tucson, Arizona, is this Boeing 747-100. It was the oldest flying 747 up until its retirement. Flown by General Electric as a flying propulsion test bed.
CN TEST RDC 1501 returns northbound towards Guelph crossing Highway 24 after testing south on the Fergus spur to Preston. This day found O999 running from Stratford to Kitchener, testing the Huron Park spur, and continuing to Guelph for this Preston trip. The train would later tie down at Guelph.
