This program simulates gravitational interactions with m1*m2/d^2 and F=ma. The demo is included in the program, but you can make your own gravitational configurations by editing the [H] matrix and loading it with the 'LOAD [H]' option.
Matrices are used to represent the objects. Each row represents an object (up to 99, the matrix limit) and each column represents a property of that object.
Column 1: The mass of the object (negative masses work too)
Column 2: The current X-position of the object
Column 3: The current Y-position of the object
Column 4: The current X-velocity of the object
Column 5: The current Y-velocity of the object
Column 6: The previous X-position of the object (used for drawing lines, internal use)
Column 7: The previous Y-position of the object (used for drawing lines, internal use)
Column 8: If circle drawing is enabled, this is the radius of the circle. (If you leave 0, the radius will be (3*mass/4pi)^1/3).
Column 9: This is the colour used to render this object's circles and lines.
This program uses the [G] matrix for internal data manipulation, and the [H] matrix for importing configurations.
Included in the ZIP is the program file, one custom configuration, and two screenshots.

Visuals (3/2): Had to give an extra point because of how nice it is at visualizing the objects.
Speed (1/2): The speed suffers quite a bit, especially if you have circles on for drawing. Still nothing too unbearable.
Ease of Use (1/2): Somewhat annoying needing to enter all the information into the matrix. I find myself needing to cross reference the matrix guide to get all the information in correctly.
Practicality (2/2): Could definitely see this being used to plot the movement of two bodies due to gravity.
Other (2/2): Nothing to comment that hasn't been said already.
