Isotope was an incredibly beautiful Siamese mix cat with fur that was cream and taupe (hence the name) and blue eyes.
I was taking college Organic Chemistry when I got her, so her name is also a nod to that. She was not, however, reactive or unstable!
Digital art created in Adobe Illustrator from the photo at left. I started with this photo, painstakingly tracing the lines and contours of the image, simplifying and stylizing where desired (e.g. the whiskers) and adding the black and ocher backgrounds.
