Name a pro basketball player or pick his team (NBA or ABA),
and see bar graphs charting

Other interactive web pages by Trow perform modular arithmetic,
including square roots; and model the trajectory of a
cannonball for different muzzle velocities and angles of
elevation, and see the projectile's flight path plotted
over time:
