The picture below is one of the doodles I did in the late nineties. I was in a waiting room of a doctor's office. A Dr. Ellen there, said it reminded her of skin cells under a microscope.
The next picture are actual skin cells as seen under a microscope. I found it on the net somewhere but, unfortunately, forgot to get the name of the medical site. I thought it interesting.
I did not draw this one. It is actually what you see under a microscope.
The next two pictures are mock up drawings, or sketches, if you will. Sorry for the quality as my scanner is not working properly.
I had to do the mock-ups when taking a color class at the university. This was for our final project and the instructor wanted documentation and notes of our thought process. We had to do an installation piece and become part of the work. They were all done in large appliance boxes which were our canvases, so to speak, and we had to sit inside the box as if we were part of it. I really wish I'd taken photos of everyone's project. They were all so different and exciting. Mine was about the two halves of me. One half being calm and relaxed and the other half being chaotic and disorganized. I actually painted half my face and my left arm lavendar acrylic paint and wore a lavendar leotard. I also painted the palm of my right hand red……for stop the madness. Somewhere, there is a slide of my final project. I have yet to find it.
My scanner is about to be thrown out. It either puts shadows where there are none or does not scan in the entire picture. Getting these scanned in with most of the picture took several tries. The printer part of it stopped working a few months back. There will be a replacement soon. Hopefully! I apologize for the smudge-like appearance on the two pictures above. They are not on the originals. Well, maybe a little but the scanner picked them up very strongly. I tried in vain with adjustments but they all looked bad. Just wanted to give you an idea of the fun installation art project.
Last, but not least, is another master drawing I did as part of my learning experience at school. I could not find a photo of the original. It is by Andrea Del Sarto. You can read more about him on wiki.
