Current, the first model of the Katra line of cybernetic felinoid personal assistants can be modified by their owners in the same way as many other electronic devices.
This is a special Hatsune Miku Mod that a fan of the Vocaloids created for their Current. As music storage and playback is a basic function of the Katra systems, this seemed like an obvious mod for the user in question. She can perform any of the music files in the users library through the Vocaloid software.
Current is about 10" high, and has had several releases with various design and hardware changes. She is currently equipped with USB 2.0, but I hear a 3.0 version may be coming soon.
Done with pentel brushpen, micron pen, colored pencil and acrylics on 8"x10" colored textured paper.
