Instant Color Change

[Epicdecoder]

Hello, I'm new to these forums and I have a question. If this isn't the right place, please say so.

About a month ago I saw a color change which was instant, and used a gimmicked card that flipped over in the center once released, thrown for example. Now that I want to look into it I cant find it anymore..? Can someone please help me where to find this one, I have a cool effect I want to do but I need this change.

Thanks for passing by,
Have a great day!

I think this may be what you're looking for, it's called FLAP by Hondo Chen. You can get the cards by emailing him or you can get the instructions here.
