The popular 1950s paint-by-numbers pastime is now portable. Aficionados who are on the go can now color paint-by-numbers images without an Internet connection or even a desktop computer. Walnut Creek, California, software developer SegTech recently introduced SegPlayMobile, a hand-held paint-by-number program for Windows Mobile 5 devices supporting the Pocket PC program environment. The mobile version adds to the company’s successful launch of SegPlayPC in September, 2006.
