App para buscar imágenes por formas y colores | Colr Flickr | Krazydad | Actionscript para juegos

KrazyDad, o Jim Bumgardner se define como un apasionado de la programación, es su hobby y su trabajo responde a ello. Programa juegos, da clases en Pasadena y trabaja para Yahoo! Music.

Esta pasión nos hace disfrutar a él y a nosotros de su trabajo/hobby. Como diseñador un poco flojo, recordemos su definición, nunca dijo que lo fuera.

De todo lo que tiene os recomiendo por ejemplo visitar esta aplicación Flash para buscar en el enorme banco de imágenes de Flickr con colores o patrones en común.

Como gurú de la programación en Actionscript es sensacional. No dejes de bajarte los archivos fuente con todo el código a tu disposición.
