I've been thinking that it would be really fun to design some imaginary pictograms for the 2086 Futurelympics- like Otl Aicher's legendary designs for the 1972 Munich Games, and Nikolai Belkow's smoother updates for the 1980 Olympics in Moscow- so I'm gonna give it a try! You might even be able to tell what sports I had in mind with these cruddy sketches, if you squint really hard.
Can you think of any sci-fi movie sports that need to be represented or made up for the occasion? I definitely think Mecha-Basketball is in order. All the action and excitement of the NBA, mixed with the total radness of Robot Jox.
