Clearing and staining, or diaphonization, is a process used by vertebrate biologists when seeking to visualize a particular animal’s skeletal system. Some steps include submerging the specimen in containers of digestive enzymes to render their organs translucent, while other steps involve immersing the animal in alizarin red dye, which adheres to calcium in their bones and stains them red, and alcian blue dye, which reacts with the cartilage of their joints. The results manage to be useful for studying biomechanical function and skeletal morphology, as well as appear stunningly beautiful.
There’s an infestation in my mind’s imagination,
I hope that they choke on smoke ‘cause I’m smoking them out the basement,
This is not rap, this is not hip-hop,
Just another attempt to make the voices stop,
Rapping to prove nothing, just writing to say something,
'Cause I wasn’t the only one who wasn’t rushing to sayin’ nothing,
This doesn’t mean I lost my dream,
It’s just right now I got a really crazy mind to clean.
Two of the above images are GIFs, so wait for ‘em to load. And I just thought of something that really ought to be mentioned; A very common mistake on drawing skulls is the eye sockets. People often make 'em smooth and solid on the inside, but it’s not accurate to have 'em completely closed off. There are holes in the eye sockets that lead to the inside of the skull, 'cause the retinas connect the eyeballs to the back of the brain (so there’s obviously an open space for the nerve to travel through). Sealed-off sockets are aesthetic, and for people who don’t want to put any more work into a tangible model of one. Just be aware of that when you’re sketching it out.
