+    isFullScreen = false
+    vSync = true
+    winWidth = 640
+    winHeight = 480
+    canViewPortX = 0
+    canViewPortY = 0
+
+    OpenWindow("CreateSprite", winWidth, winHeight, isFullScreen, vSync)
+    sCanvas = OpenCanvasSpriteLayer(canViewPortX, canViewPortY, winWidth, winHeight)
+    Canvas(sCanvas)
+
+    DIM eye
+    DIM eyeW
+    DIM eyeH
+
+    eye = LoadImage("theEye.png")
+    GetImageSize(eye, eyeW, eyeH)
+
+    eyeSprite = CreateSprite(eye, eyeW, eyeH)
+    SetSpritePosition(eyeSprite, 100, 100)
