The first web page built by PositLog was published on May 29, 2006. It was equipped with basic functions such as those for creating sprites, arranging them anywhere, dragging a page to scroll, and plug-ins. The source code of version 1.0 was distributed on June 5, 2006. It won the prize for the best presentation at MYCOM2006 (supported by the Japanese Society for Artificial Intelligence). Version 0.52, which has a hand drawing function, was registered with SourceForge.jp on May 2007, and since then, it has become popular.
