Customized Ring Generator

You can also create your own customized and personalized ring using this tool.

Simply change the URLs and descriptions to suit your needs and to change the icons, drag&drop to reorder the list, and add or delete the ring items. You can choose from a collection of ring items to include in your own personalized ring.


In Safari, bookmarks placed on the bookmark-bar can be opened using Command + number. So if you place the G-language Bookmarklet to be the left-most bookmark on the bookmark bar, you can press Command + 1 to invoke the ring anytime.

Alternatively, in MacOS X, you can assign keyboard shortcuts from the "Keyboard" preferences panel in the System Preferences. Here you can set your own key combination to load a bookmark.

Supported Browsers

G-language Bookmarklet utilizes several features of HTML5 (round-rect elements, drop-shadow effects, and Audio() class). In order to use full functionality, use Firefox 3.5 or above, or Safari 4 or above.

Chrome works ok but without the sound effects (Chrome does not have codec for WAV files).

Internet Explorer has poor support for correct HTML/Javascript/CSS, and does not support HTML5 audio. We have no plans to support/test on IE, but G-language Bookmarklet should basically work.

Development Philosophy and To Dos

You can find these information at the BioHackathon2010 site.


The basic idea of ring menu comes from the "Ring Command" interface of the game "Secrets of Mana" (聖剣伝説2) by SQUARE ENIX CO. LTD.

Basic javascript implementation of the Ring Command is adopted from the NavigationRing.

Sound for the Ring Command is taken from SKLaunch.
