Created as a Master of Science thesis by a Computer Science student in Umeå University, Phun is an amazing little educational game giving players a rich physics playground where they can easily build and tear apart environments, creating havoc upon squiggly line blocks, water, bits and so much more. Great for teaching a young class about the concepts of physics or just a fun little toy to waste your time at work.
