I read about using meaningful materials in the textbook on page 258.  This is a Folk Art Lamp made out of Popsicle sticks.  I would say this piece looks pretty intricate to begin with, but the fact that it's made out of Popsicle sticks makes it seem so much more of an accomplishment.  Three dimensional art often uses in-expensive materials, like this one does. 

So...this video blew my mind.  All one take, I believe, which is insane if you watch all the way through.  They used drones to film the above shots, and at the very end you can notice the camera view goes all the way from the ground surface to the clouds.  Officially glad to have seen this video!

Addressing contradictory textures from page 204, this is a cube that I thought represents this concept.  It is an obvious cube, yet at the same time it's made up of slender curved sheets of metal.  When I think of a cube, I think of a box, or a crate; something uniform and possible dull.  The texture of this cube is shiny, sleek, artistic, curved, and rounded.  For me, this is a contradictory piece. 

Three dimensional design is the next subject that intrigued me.  There is something the book refers to as "dynamic form" where the structure implies movement.  I think this piece accomplishes that with its curvature, texture, and sleekness. 
When I look at this, I think rippling waves, wrinkling fabric, or something along those lines.  At the same time though, it strangely doesn't look exactly like any of those!  A clever piece, in my opinion.

Not sure how to upload a PowerPoint Presentation but maybe, just maybe, there might be one linked above.  I'm attempting to share a presentation I made on a crazy lighting guy named Austin Richards.  There is is a cool video linked within of his work with Tesla coils.  If the link doesn't work, please let me know.  Especially if you one of you knows how to share a PPT. presentation.     

Transformation in art works with physical form, and greatly relies upon the materiel with which it is made of.  In light of that, I think I found the coolest example out there (in my opinion); Bumblebee from Transformers made entirely out of recycled material!  This goes to show that you can make something incredible, like a high-tech-looking robot from outer space out what was once essentially trash.  Below is the piece referenced.  :D
