A silver aluminum light pen with a black plastic tip pressed against the glass screen of a Tandy CM-II CRT display. Beneath the tip is a small cyan arrow cursor, above a large magenta circle. Inset in the circle is an outline of the text "hello" trailing off the right side of the screen. The blue overscan color is seen in the lower left, with a few cyan lines.
