Still in Singapore, waiting n learning

Still in Singapore on Monday 11 May due to H1N1 scare in US. Waiting for 2 more weeks to see how the situation develops.
Meanwhile, my first successful attempt on dynamics, though still with some problems...

Summary: 3 RBD corner bricks were created. Rest of the brick wall was modelled and made into a static RBD. Ground plane needed to 'catch' the falling bricks. A sphere was animated to hit the 3 corner RBD bricks. This sphere was hidden and a second sphere was animated to look like it hits the bricks and goes on. Needed this second sphere because if the first was animated to hit and follow through the bricks would crash out too far. Wanted it to fall near the wall. Dust effect was created with a smoke container and a box geometry made into a smoke source. Temperature ramp was made negative so tends to fall downward. Finally, one of the bricks emits some particles for debris.
