REDWOOD CITY, CA -- (MARKET WIRE) -- 12/18/09 -- Graffiti Entertainment, Inc. -- a subsidiary of Signature Devices, Inc. (PINKSHEETS:SDVI) -- today announced that it has donated 15 of its highly successful 'Reader Rabbit Kindergarten' for the Nintendo DS(TM) interactive learning Games to GETSET-GO (Girls' Empowerment Through Sustainable Educational Technology, Giving and Organization).

Kenneth Hurley, Chief Executive Officer of Signature Devices, Inc., parent company of Graffiti Entertainment, explained that "...this donation through Graffiti Entertainment came about when the President of GETSET-GO -- Daniel Ostenso -- contacted me to request 'Reader Rabbit Kindergarten' for his project in Cambodia (beginning in January), using the Nintendo DS(TM) system. Since Graffiti Entertainment has just released the 'Reader Rabbit Kindergarten' title, and especially since we're dedicated to providing learning materials that educate and inform young people, it was a perfect fit. GETSET-GO, being a non-profit with limited funds, well... we were glad to do whatever we could to help out." GETSET-GO focuses on educating girls in developing countries -- with a particular emphasis on using practical and sustainable educational technology -- often in rural and poor areas where schooling for girls is badly needed.

In thanking Mr. Hurley's generosity through Graffiti Entertainment, Mr. Ostenso wrote: "You will be helping to make a tremendous difference in girls' lives (and in their communities'). Whether we're talking about improvements to health, economy, social stability and national security...you name it -- Education is the seed from which they all grow. And investing in girls' education tends to generate the highest returns."

The Reader Rabbit Series has been captivating children for over 20 years with the finest interactive learning products in both schools and homes, having sold over 6 million copies since 1993, and winning 175 awards and accolades! Reader Rabbit Kindergarten has been designed to interest children and encourage learning of basic kindergarten skills such as mathematics, phonics, reading, and listening in multiple contexts.

This Reader Rabbit series is comprised of grade-based and subject-based titles aimed at children from infancy through second grade. Reader Rabbit is the main protagonist and goes on various adventures usually involving educational mini-games. As the name implies, Reader Rabbit's initial focus was on teaching young children basic reading ability, however the success of the series has led to math games and a series of grade-based (e.g. preschool, kindergarten, 1st and 2nd grades) games that cover various subjects including basic reading and phonics, math, memory, and other skills including:

-- Activities involving exploration -- Comprehension, listening, and thinking activities -- Practice games in an arcade style
