Contiki is a highly portable, Open Source OS complete with a GUI, multitasking and a TCP/IP stack and only requires as little as 2KB of RAM. It is used in many embedded systems, and has been ported over to many 8-bit vintage systems, making it an OS popular in retrocomputing.
The first microcomputer port of Contiki is the Commodore 64 version.
Contiki-tan is represented as a small girl with wavy light blue hair and blue eyes, her hair is decorated with flowers, wears sunglasses and her outfit has a tropical theme to it. She wears a sleeveless shirt with a sailor collar, a tie-dye skirt, shorts and sandals with wooden jewelry. What she wears is in the color schemes of several of Contiki's ports, her skirt is in the color scheme of the C64 version. In her 'human-sized' form, she is 120 cm, but can shrink herself down to the size of the Damn Small-tans, if not even smaller to fit into and fix small devices, while referencing the extremely low hardware requirements.
She is mild-mannered, adventurous, very social, and is a surfer with a love for environmental science and cultural anthropology. She is a close friend and ally to the Binteeji Renmei, but lives as a wanderer because she travels so much. Curiously, one of her friends is the very hot-headed Tiny OS-tan, who Contiki-tan always tries to get to travel with her. While the two of them argue a lot, they consider each other friends even though Tiny OS-tan won't admit it.
