 Different shapes
 
 Complete all modes except practice and multiplayer and achieve an
 "OK" rating. Once you get an "OK" rating on all the required
 sections, the background color will turn green. Select any game mode
 other than practice mode. Then you will see a little blue guy. Select
 him and push a button to change him into a duck. Now when you start a
 game, the tedrads will be triangle, rectangular, and square-shaped
 pieces. 
 
 Floor select and change background color
 
 Complete all 16 practice rounds. Then, go to the options screen and
 there will be a new option called "Floor". This will let you chose
 from many different floor sets, such as the Mona Lisa and the
 American Flag. Also, this changes the background color of the
 title/options screens.
