## Examples

### Path follow animation

```Go

ctx := gog.NewContext(250, 100)

rect := shapes.Rect(v.Vec{}, 30, 10)

lemn := shapes.Lemniscate(100, 100).SetPos(ctx.Center)

lemnTotalLength := lemn.Length()

for _, length := range utils.Linspace(0, lemnTotalLength, 120) {

  ctx.Clear(color.Black)

  ctx.Stroke(lemn, gog.DefaultStrokeStyle())

  pos, ang := lemn.PointAngleAtLength(length)

  ctx.Fill(rect.SetPos(pos).Rotated(ang), color.White)

  ctx.AppendAnimationFrame()

}

ctx.SaveAPNG("path_follow.png", 2)

```
