Hello There, I have an animated rotating 3d looking cube. It is going to be a logo for a shmup. Anyways I want it to animate off the screen with realistic gravity as it continues to rotate. I find geometry not hard but realistic gravity examples like Pharaphs Physix confusing for some reason, especially since I have an animation going on at the same time:

```
#include <Arduboy2.h>
int horizSpin = 64;
int vertSpin1 = 88;
int vertSpin2 = 40;
int SpinRad = 38;
Arduboy2 arduboy;
void setup() {
arduboy.begin();
}
void loop() {
arduboy.clear();
for (int i = 60; i > 0; i--) {
arduboy.fillRect(0, 0, 128, 64, BLACK);
arduboy.fillCircle(horizSpin, vertSpin1, (SpinRad / 2) - 1 , BLACK);
float SpinAng = i * 6;
SpinAng = SpinAng / 57.296;
float SpinAng2 = SpinAng + 90 / 57.296;
int a = (horizSpin + (sin(SpinAng) * (SpinRad / 2)));
int b = (vertSpin1 - (cos(SpinAng) * (SpinRad / 2))) / 2;
int c = (horizSpin - (sin(SpinAng) * (SpinRad / 2)));
int d = (vertSpin1 + (cos(SpinAng) * (SpinRad / 2))) / 2;
int a1 = (horizSpin + (sin(SpinAng2) * (SpinRad / 2)));
int b1 = (vertSpin1 - (cos(SpinAng2) * (SpinRad / 2))) / 2;
int c1 = (horizSpin - (sin(SpinAng2) * (SpinRad / 2)));
int d1 = (vertSpin1 + (cos(SpinAng2) * (SpinRad / 2))) / 2;
int e = (horizSpin + (sin(SpinAng) * (SpinRad / 2)));
int f = (vertSpin2 - (cos(SpinAng) * (SpinRad / 2))) / 2;
int g = (horizSpin - (sin(SpinAng) * (SpinRad / 2)));
int h = (vertSpin2 + (cos(SpinAng) * (SpinRad / 2))) / 2;
int e1 = (horizSpin + (sin(SpinAng2) * (SpinRad / 2)));
int f1 = (vertSpin2 - (cos(SpinAng2) * (SpinRad / 2))) / 2;
int g1 = (horizSpin - (sin(SpinAng2) * (SpinRad / 2)));
int h1 = (vertSpin2 + (cos(SpinAng2) * (SpinRad / 2))) / 2;
arduboy.drawLine(a, b, a1, b1, WHITE);
arduboy.drawLine(a1, b1, c, d, WHITE);
arduboy.drawLine(c, d, c1, d1, WHITE);
arduboy.drawLine(c1, d1, a, b, WHITE);
arduboy.drawLine(e, f, e1, f1, WHITE);
arduboy.drawLine(e1, f1, g, h, WHITE);
arduboy.drawLine(g, h, g1, h1, WHITE);
arduboy.drawLine(g1, h1, e, f, WHITE);
arduboy.drawLine(a, b, e, f, WHITE);
arduboy.drawLine(g, h, c, d, WHITE);
arduboy.drawLine(a1, b1, e1, f1, WHITE);
arduboy.drawLine(g1, h1, c1, d1, WHITE);
arduboy.display();
}
```

Thanks to you all.
