"I really appreciate that you have re-done this mathemagics trick.
I love to it at the start of the year.
Is there anyway you could put sounds in - like the older flash version?
Apologies if you already have, but I can't hear them.

[Transum: Yes there is a sound effect when the picture is revealed. I'm not sure why you can't hear it.]"

"I, after searching for a formula for this for a long time, found out the reason it mind reads you. For the sake of Transum, I won't be telling the solution."
