Cascade first try: Grenade Explosion

To familiarize myself with cascade I attempted a grenade explosion limiting myself to the square, circle and triangle shaped materials. I am also limited to only using these in cascade: 

Acceleration > Acceleration Drag
Color > Initial Color, Color Over Life
Lifetime > Lifetime
Light > Light
Location > Initial Location, Shapes
Rotation > Initial Rotation
Rotation Rate > Initial Rotation Rate
Orientation > Lock Axis
Size > Initial Size
Velocity > Initial Velocity, Velocity Over Life, Cone

Might not look much to the world, but I learned a lot poking around in Cascade. Will attempt bullet impacts next.
