#C2C15 Seeing and Not Seeing

I have somehow completed the third sketchbook theme early. This is "Seeing and not Seeing".
All five of my double page spreads are in the box below; click left or right to move through them:


The images are:

Big Yellow Taxi (double page)

Because, "Don't it always seem to go / That you don't know what you got 'til it's gone."
Acrylic and Derwent Drawing Pencil.

Interference and Spectacles

The former is a physics experiment that demonstrates how light waves interact (reinforcing and negating each other); and the latter make all the difference between seeing and not seeing if you're short-sighted.
Graphite and acrylic; Derwent Drawing Pencil.

Eyes (double page)

I am more shortsighted in the left eye; this is, of course, a mirror image. I portrayed the left eye without glasses and with an excess of water. The idea was to create a blurry image; the dribbles were a bonus. I was more measured in my treatment of the bespectacled right eye.
Watercolour.

Schrödinger 's Iron Man (double page)

Science meets art with bonus Black Sabbath. Schrödinger's cat is a thought experiment that uses observation to "fix" a previously indeterminate state (is the cat alive or dead?). The atom just happens to be Lithium (added Nirvana?).
Mixed media.

Painty Water (double page)

I see therefore I paint (and draw). The murky water in the jar obscures and distorts the paintbrush(es) and, in the final view, the lettering on the place mat.
