This is a very nice piece of source code to keep in your personal AJAX toolkit. “Prototip allows you to easily create both simple and complex tooltips using the Prototype javascript framework.” It’s very easy to use and works in all browsers.

Tag Galaxy is another in a long line of Flickr API visualizations. While I’ve seen several tag based visualizations for Flickr this one is particularly playful. You can move the globe, click on an image, and see more information about the photo. Most of the other tag visualizations for Flickr that I’ve seen when you click on the image to see a larger size, or learn more you leave the visualization and go straight to Flickr. I like that you stay in context with Tag Galaxy to view more. The project was created by Steven Wood of Georg-Simon-Ohm University of Applied Sciences Nuremberg. Nice work.”

SocialHistory.js, code enables you to detect which social bookmarking sites your visitors use. How does SocialHistory.js know? By using a cute information leak introduced by CSS. The browser colors visited links differently than non-visited links. All you have to do is load up a whole bunch of URLs for the most popular social bookmarking sites in an iframe and see which of those links are purple and which are blue.

“One can find it on almost all products: the bar code. Everyone knows that the bar code is used to facilitate the cashing and recording of goods in stores. But which information is actually encoded within the bar code? A simple answer to this question can be found at one of the product databases on the Internet, which are basically huge networks of national code databases. Keying in the 8, 12 or 13 digit figures of a bar code into an international code database, returns information on the manufacturer and the country of origin of the product. Moreover, each bar code is assigned to only one product worldwide; but these individual details are hardly visible to the naked eye.”Visit the website

In this tutorial Nettuts takes as they say,”an average everyday website and enhancing it with jQuery. We will be adding ajax functionality so that the content loads into the relevant container instead of the user having to navigate to another page. We will also be integrating some awesome animation effects.” Very fun AJAX tutorial.

DimP is a video player prototype that allows to browse video clips by directly manipulating their content. The way it works is quite simple. First, DimP automatically extracts object motions from the videos and then allows the user to control video playback by scrubbing these objects on their trajectories.

Image driven scholarship is a lofty goal, however, MIT’s Visualizing Cultures has created a wonderful visual learning space. I spent quite some time tonight going through the site and throughly enjoyed it. As they state, ” Visualizing Cultures was launched at MIT in 2002 to explore the potential of the Web for developing innovative image-driven scholarship and learning. The VC mission is to use new technology and hitherto largely inaccessible visual materials to reconstruct the past as people of the time visualized the world (or imagined it to be). I love the idea and the site, however, the top drop-down menu at the top of the page started to bother me over time. Since this is the main navigation for the site it might be nice if it was a breadcrumb rather than a poppy drop-down. I still like …

“A nice visualization by Akshay Java of network analysis of Twitter. “The following is a graph constructed using contacts from about 25K users. Notice that there is a link connecting two users if either one has the other as a friend and hence it is an undirected graph (of about 250K edges).”Visit the website

UbiGraph is a tool for visualizing dynamic graphs. The basic version is free, and talks to Python, Ruby, PHP, Java, C, C++, C#, Haskell, and OCaml. Version 1.0 is distributed as two separate components. The server application, which renders graphs, is distributed as a compiled binary. The client bindings, which use XMLRPC, are distributed under an open source license. The software uses dynamic, multilevel graph layout for quick convergence of graph layouts. It uses XMLRPC for cross-language and distributed graph support, OpenGL for rendering, and Pthreads for parallelism. The software is also free and easy to use.”
