Branovets Games has introduced Demolition Physics 1.0 (http://macte.ch/23LOf), a demolition simulator for Mac OS X 10.6.6 or later. It costs US$4.99 and is available on the Mac App Store in the Games category.
Demolition Physics offers 3D simulation for each type of explosive from the fiery trail to the atomic explosion. Each explosion has its own distinctive features and different impacts on the destruction.
Additionally, the special effects are connected, such as depth of field, motion bur, and others. Slowing down time will allow more details to see the interaction of objects in the explosions. In addition, play with ragdoll physics.
