Bonus assignment!- I suggest trying this on different shapes to merge this understanding with the first assignment. Try this same process with;

• Spheres
• Donuts 
• Cylinders
• Cones

Some people have tried putting context to the cubes, such as drawing and rendering out dice, a Christmas gift, and -ooh! A companion cube from Portal 2 would be pretty dang cool.

• HARD MODE: 
  Draw and render all 5 of these Tetris blocks in a scene with a light source of your choosing. They can be arranged however you like - floating, stacked, radial arrangement - it's up to you!
  
  
• LEGENDARY MODE:
  Render an exploded view of the MedCube of your choosing, each cube section is floating away from one another (with 27 cubes total), with a light source casting shadows onto other cubes. 
  <--- "exploded view"
