See the widget at the right showing if your browser+computer supports WebCL?
It is available under the GPL 2.0 license and based on code from WebCL@NokiaResearch (thanks guys for your great Firefox-plugin!)
Download from WordPress.org and unzip in /wp-content/plugins/. Or (better), search for a new plugin: “WebCL”. Feedback can be given in the comments.
I’d like to get your feedback what features you would like to see in the next version.
