It's a very primitive game that opens a small window in which the
user can draw lines with the Up, Down, Left and Right buttons.
The color buttons are used to switch color.
+
+On a VDR system with TrueColor support it displays some of the
+possibilities available with the TrueColor OSD. Once the "Animation"
+pixmap is displayed, it can be moved around with the Up, Down, Left
+and Right buttons. The Red button turns off the "Tiled Pixmaps"
+display, and the Green button toggles the color display.
+
Press Ok to close the window.
