Here is a quick ROKU 3 example, since I don't have your will power. I unplugged my 2XD

 
   Screen = CreateObject( "roScreen", True )
   Screen.Clear( &hFFFFFFFF )
   Screen.SwapBuffers()
   
   bitmap = CreateObject( "roBitmap", { width: 200, height: 200 , AlphaEnable: False } )
   bitmap.Clear( &h911820FF )
   width  = bitmap.GetWidth()
   height = bitmap.GetHeight()
   region = CreateObject( "roRegion", bitmap, 0, 0, width, height )
   
   x = int( width  / 2 )
   y = int( height / 2 )
   region.SetPretranslation( -x, -y )
   
   for theta = 360 to 0 step -1
      Screen.Clear( &hFFFFFFFF )
      Screen.DrawRotatedObject( 100 + x, 100 + y, theta, region )
      Screen.SwapBuffers()  
   end for
