Sankaku Channel/wacom

Wacom is a loose transliteration of Japanese: Wa for "harmony" or "circle", and Komu for "computer". It is one of the largest graphics tablet producers, and is very popular with artists, graphic designers, architects, and cartoonists, who commonly cite it as an industry standard. Wacom tablets are notable for their use of a patented cordless, battery-free, and pressure-sensitive stylus or digital pen.
