"Crazy Frog Racer" European Video Game Sensation Launches in North America by Signature Devices' subsidiary Graffiti Entertainment, LLC.

The Outrageously Popular "Annoying Thing's" Video Game Leaps Across the Pond May 17th, 2006 as Part of Major Rollout

SUNNYVALE, CA - May 4th, 2006 - Signature Devices, Inc. (OTC-PINKSHEETS: SDVI; www.signaturedevices.com) interactive game publishing subsidiary Graffiti Entertainment LLC (www.graffitientertainment.com), on May 17th, 2006, will launch the PC version of the video game in North America that features Europe's most outrageously popular animated character, "Crazy Frog" (www.crazyfroggame.com). Releases of console versions are scheduled later in the year.

"Crazy Frog Racer" is the third video game the company will market since forming its publishing subsidiary last month. It previously announced worldwide publishing rights to "Mazes of Fate" and "Strike Force: Red Cell", that are soon to be released.

The high-speed, high-octane wacky racer game, Crazy Frog Racer (http://www.crazyfroggame.com) is licensed from Mercury Games Ltd. It is based on the phenomenal success of the animated cell phone ring-tone frog-like character "The Annoying Thing™" that aggravated his way into mainstream popularity - starting with 12 million ring-tone downloads worldwide. The Crazy Frog Axel F single tune has reached number one in over 20 countries. Its album received 2.5 million pre-orders in the United Kingdom alone. The Crazy Frog Racer video game that is being introduced here was this past Christmas' number one seller in both the Playstation and All Formats in the UK.

As part of its North American debut, the Cartoon Network will be running the Crazy Frog music video that features the Axel F Tune. It has already been the most requested song on Disney Radio for several weeks. Over 60 merchandise items that range from MP3 players, radios, and plush toys will be launched in May to US retailers that include Wal-Mart, Best Buy, and Target. Jamster, where the phenomena started, is providing ring tones for the US market. Graffiti Entertainment is making available a free download to the Axel F Music Video and game preview at http://www.graffitientertainment.com

"Our ability to acquire publishing rights from superior developers, especially those with a franchise character as well known and popular as Crazy Frog, clearly demonstrates how rapidly we have made the transition from developing games for some of the best known publishers, to becoming an integrated developer and publisher of world-class interactive entertainment games for the most popular platforms," says Ken Hurley, CEO of both Signature Devices and Graffiti Entertainment." We are extremely pleased that Mercury Games selected us to publish its Crazy Frog Racer game throughout North America. We are delighted to work with them to build the Crazy Frog brand franchise by successfully marketing the Crazy Frog Racer game here."

The Crazy Frog Racer game features the wild amphibian and his friends in a madcap ride through cities and underground chaos, blasting opponents while grabbing zany power ups, and super boosts. Its special features include:

· Over 8 playable characters, including the one and only Crazy frog and unlock many more!
