Made some test cards that you see (or used to see) on the television.
This one I made a while back uses a BBC test card - it would’ve had an image of a little girl playing naughts and crosses (tic tac toe I think you guys call it), with a little clown toy called Bubbles.
The next two are test cards I made myself and include my avator in the centre - these cards a loosely based on the Philips circle pattern also referred to as the Philips pattern or PTV Circle pattern.

Without text:-
I also made one using the ghosts (one edited) you see on the popup targets you see in the Dark Voyage ride. The lower one has no text.
Here’s a blank one which has a transparent circle in it so you can place you own image in it (both text and non-text versions).
If you do decide to use the blank ones, please give credit. Thank you.
