Physical Interactions

What are some physical interactions that could be incorporated into the following systems.  Do not need to concern self with practicality with ideas. 

Email

• Have an object shaped like an envelope which you physically pick up and open to open an email. 

• Have physical cards to represent the emails, then a set of physical inboxes to represent folders - maybe a file-a-fax. 

• Scrunch up an email and throw it in a physical bin.

Twitter

• Tweets on index cards

• Post-it notes - you get a stack of them and then you have a corkboard to place the ones you like on, like keeping quotes or notes and pictures from your friends.

• Have little figurines which represent your friends/people you follow and you place them on a particular spot/stand to view that person's feed.

Super Mario Bros

• Have a trampoline to bounce on to get Mario to jump. 

• A seesaw you can jump on, rock side to side to get Mario to walk and jump to jump

• Have a physical puppet which you walk and bounce around.
