OshinView is a graphical sequence editor, inspired by SeaView. Loaded sequences can be represented in a spiral form, which can sometimes help with repeat detection and filling space on the page. This is a JavaScript program that uses your own computer's resources; sequences are stored locally on your computer (in-memory, with a possible future implementation using localStorage), and JavaScript code is used to display and manipulate the sequences.
