It’s fun to think what Warhol may have done with digital and social networking tools. I can see a mash-up of Four Square and his famous Warhol effect with maybe each square placing the image in a different location.
Nothing so interesting with my first Warhol effect. I did use GIMP to create my first and then tried a “toy” on the BigHugeLabs site to generate the poster. I learned from the machine-generated Warholizer that a more abstract effect is more appealing — and takes 20 years off!
