I guess utopia for designers will be a place where they can sketch on paper using a pen that has built in tools of Color Markers, Tablets and Adobe CS. Not yet there, but relatively close, the PLUM concept, designed by Yeban Shin, is a pen that features a CMYK ink cartridge and is mixed with microfluidic technology to create a specific color that is desired. As you sketch, your drawing gets auto saved to a micro SD chip in the pen’s cap. Naturally, you hook up the cap to a computer and get editing on your design. Select four different pen tip sizes: 0.3, 0.5, 3,7- mm size.
