While at an Office Depot this drippy morning picking up supplies with gallery owner Luis De Jesus, Hugo and I daydreamed the future of painting without paint:

The idea was that there would be a “smart” primer gesso substance which could be applied to any surface. It would be inert (no currents running through it) until it’s programmer/painter touched the surface with finger/hand/body part. Only then would the surface activate- change of color would appear.
The programmer would have their own unique palette of colors and would be the only one able to make any mark on the “smart” primer. The person would be the source of energy and would provide the other half of a code string (or something like this) which would activate the desired colors. How would the colors be differentiated? Pressure and heat senses are the obvious ones, but what if the paint was smart enough to recognize the  hormonal difference between the the artist on a good day versus a bad day or the  structural difference between an elbow and the the nail of the pinky finger of the left hand? -Colors could be assigned to each part! How much fun would that be! …
I hope some else out there catches the idea and the spark of creative will to make it happen.
Though it is essentially finger painting, I still think that for artists it would be a useful marriage of science and fine art- the the right hands – as it were.
It would be incredibly difficult to make a forgery of an artists work!
And it would be literally something coming from you and you alone. No one else could make that mark. For better or worse.
So this was my brain running along with Hugo’s thoughts into what little I know of biometrics and nano paint tech. And I have the time to sit and dream it out further and blog about it! That is an amazing thing to me right now. I am on vacation! I can have time for my daydreams. Yay!
