Art inspired by Andy Warhol and Keith Haring is available from Apple in the form of iCards.

San Francisco-based artist John Kraft has joined Apple's Featured Artist Programme.

The programme provides an in-depth look at a body of work by established artists, and according to a press release issued by Kraft: "This exposure, which extends through the summer, has already led to increased recognition of Kraft's work both domestically and abroad."

Kraft's style is described as "unique and playful, but with a mature edge". He uses vibrant colours and strong black lines.

"I believe a key aspect of the creative process is the desire to share one's work with the widest possible audience," says Kraft. "Through the production of Giclee prints and the use of the Internet, I hope to share my work with a larger audience over a wider geographic area."
