FunIntGra
FunIntGra, or Function Intersection Grapher, is a program that graphs with 3 time variables. The results, which I call FIGs, can look cool like this background. It can also graph with a z element instead of intersection highlight. That makes something like:
Now isn't that interesting? Now for what the different buttons do:

Render | draws the FIG.
Formula X,Y,or Z | changes the formulas.
Range Min | changes X,Y,or Z time range start.
Range Max | changes X,Y,or Z time range end.
Range Skip | changes X,Y,or Z time range detail.
Color Red, Green, or Blue | changes the R,G,or B for the selected color.
Color # < or > | changes which color is selected.
Style # < or > | changes styles.
Pow # - or + | adds or subtracts from the color power.
Load | loads a FIG from the gallery.
Save | saves a FIG to the gallery.
Screenshot | takes screenshots from shot0 to shot 8 to shot 9237 and on.
Exit | immidiently terminates the FunIntGra program execution.

When you render, a loading bar shows the progress. When rendering, pressing escape stops at the current point. Pressing F1,F2,or F3 shows the action at 3 different speeds.
Formula syntax is as follows in operating order:

( and ) | Parenthesis.
P,G,&R | Puts down pi, the golden mean, or a random number from 0 to 1. *(e.g. 2P or R)
X,Y,&Z | The three time variables are substituted here. Note the capitalization.
S,C,&T | Retrieves the sine, cosine, or tangent of the following number. (e.g SY or C(X*3))
^ | Raises the first number to the power of the second. **(e.g. 10^2 is 10 squared)
* and / | Multiplication and Division
+ and - | Addition and Subtraction

*In all other cases, you must put 2*X or 2*(23), but not 2X or 2(23)...
**The nth root of X can be figured by X^(1/nth). (e.g. 16^0.5 is the square root of 16)
A formula example is CX+S(X^0.333333)/P which is the cosine of X plus the sine of the cube root of X over pi.
An example of the order is 2+3*4. Since Multiplication is higher, it comes first. So first, 3*4=12; then 2+12=14.
Style is either 1, which highlights a point according to how many times it has been crossed, or 2, which utilizes the Z formula to describe the brightness at a particular point. Examples of each are in the gallery, where all FIGs are stored.
The 4 colors control fading. As a pixel gets brighter, it fades from color 1 to color 2. When it passes color 2, it fades to color 3. This proceeds up to color 4.
On the load screen, you can press del to delete a FIG.
On the save screen, New File will then ask you to type in the name for a new FIG. WARNING!:Saving will overwrite files without asking.
Taking a screenshot places the image in the 'Screenshots' folder.
If you want a huge 'Poster Print' of a FIG,
(1)Zoom in say maybe 2x by multiplying the formulas by 2,
(2)Move up and left one by adding 1 to the formulas,
(3)Take a screenshot.
(4)Change to up and right one,
(5)Take a screenshot.
(6)Change to down and right one,
(7)Take a screenshot.
(8)Change to down and right one,
(9)Take a screenshot.
(10)Put the screenshots together.
You might want to adjust detail and color power after zooming in. For an example of a big picture, look at PolarWeb(Grande).bmp in the screenshots. I had to double detail (half the Skip) and double the Color Power.
Have Fun!
