NAME
timmy - physics sandbox
SYNOPSIS
games/timmy [ -s steps-per-frame ]
DESCRIPTION
Timmy is a simple 2D physics sandbox.
To pick up an object click on it with mouse button 1. New
objects can be created by picking up their archetypes in the
gray area on the bottom (the "tray"). To place an object in
the working area click at the desired position with mouse
button 1; timmy will refuse to place the object if it would
collide with an existing one. To abort the process - delet-
ing the carried object - click anywhere with mouse button 3.
Picking up an object in the working area with mouse button 3
will duplicate the object.
The following operations can be performed with the keyboard.
w Rotate carried object by 15° to the left.
e Rotate carried object by 15° to the right.
space
Start or stop the simulation.
del Exit timmy.
The small circles on some objects are "hinges". Two hinges
can be connected by placing them on top of each other.
Their relative position will not change during the simula-
tion; objects are however free to rotate around them. To
undo a hinge, pick up either of the objects.
The -s option adjusts the speed of the simulation; only
integer values are permitted. It does not compromise accu-
racy.

BUGS
Timmy's physics may occasionally appear to originate from
another universe.
-s is a hack.
