If art students could have one wish, it might be this. The Pluma pen prototype has a built-in dispenser of changing colors. It gives you a color picking option as well as an adjustable tip size. Furthermore, everything you sketch with this pen can be saved on to an micro SD memory card. The data can also be uploaded to Adobe, so there is no need for a scanner.
This high-tech pen uses CMYK ink cartridges that printers use. It also incorporates microfluidic technology, which is commonly used for medicinal practices. This artistic device is USB chargeable and its contents can be uploaded to tablets as well as computers. The prototype seems almost too advanced to be called a pen.
