Phun is now known as Algodoo, and is part of the family of applications offered by Algoryx, a company that develops multi-physics and 3D simulation software. As you can see from the recent video below, it has improved over the years. The most recent news is that the application was transformed for use on the SMART Board 800 series, and supports multi-touch and multi-user interaction.
One of the reasons that I like Algodoo is that it supports social interaction during learning activities, something that can enhance deeper learning among students. It allows students to move and work in a "hands-on" fashion. In schools that have invested stimulus money on technology and now have limited funds for upgrading traditional science equipment, applications such as Algodoo will most likely provide a good "bang for the buck".
Algodoo: Science education for a new generation
"Algodoo is a totally unique program. A program that gives you the opportunity to play with physics - using your own hands. Apply a constructionists learning paradigm, learning by doing. Use simple drawing tools to design, construct and explore with. Sounds like an interesting idea? Watch this video and learn how!" -Algoryx
