Intel Mash Maker lets you mash together bits and pieces of them web, as if it were your own personal canvas. The tool which comes from the chip making monolith, is currently offered as a free browser extension for Firefox and IE (with more features for the former). Once downloaded, users can modify web pages, combining info from a range of sources. All of this occurs on the client, so you’re not making a brand new web app per se. You are adding visualizations etc via widgets. So basically, the masher allows you to customize a page by creating or modifying widgets to different web pages. Customization is thus on offer to everyone, not simply tech nerds. There is a gallery where you can find popular widgets to customize for your own use.
