In very simple terms, the POV globe is a ring of RGB LEDs that is rotated axially at high-speed (300 rpm). Due to this high-speed and the phenomenon of persistence of vision (POV), our brains interprets this moving ring of light as a solid, spherical surface. By changing the colours of the LEDs very quickly, we can display images on this spherical surface. Mounted inside the ring is a Raspberry Pi (RasPi), a small, single-board computer that has become popular in the last couple of years. Its small-size and lightweight design make it ideal for this application. The RasPi has an HDMI output and therefore a custom FPGA-based HDMI decoder was designed and implemented for this project. The decoder takes the HDMI signal and converts it into a form suitable to be displayed on the ring of LEDs.

Visualise your data in different ways. Each of them animated, fully customisable and look great, even on retina displays.

Explore analyses of popular songs, or contribute an analysis of your own.

TeamWall will display only the important information your team needs on a big screen. It rotates through all of them and one can jump to a specific one if needed. It’s display is designed to be readable from all across the room by all team members.

TeamWall is a great tool for your team of programmers to get condensed information about your code base. It integrates with data providers like Sonar, Jira or Teamcity to get the information you need.

The maven-dependency-graph plugin generates a transitive dependency graph of a maven project. This can be helpful in identifying unnecessary and unwanted dependencies.

The plugin generates a graphml file that can be viewed using a tool like www.yworks.com/products/yed

In this blog entry, I present a maven plug in that generates an XMI model from a pom.xml file and it's dependencies. XMI is an XML standard most commonly used to represent UML models. Most professional modeling tools can read XMI files. The XMI itself is not directly a visualization of the dependencies, but with a decent modeling tool, all kinds of fancy visualizations are possible.

Tom Guilmette spent a productive evening locked in a Las Vegas hotel room with a Phantom Flex high-speed/high-def video camera, taking high-speed footage of water, breaking glasses, himself jumping on the bed, and other everyday phenomena that become amazing and dramatic when slowed down to wachowskiian speeds and cleverly edited.
