The Amazing Card Magician

First, put Rick Superb in the mind-reading chamber with his pen. Close the door so he can't see what's going on. Then, let your friend choose a card. Open the door, and walla, Rick has written the chosen card on the wall!!

Here is a demonstration video, so you get the idea.

*Please note that Rick uses a whiteboard marker, to make sure that no brick is damaged through the trick.

This lego set has voice recognition!!!

Figure 2 shows the secret code used to communicate the chosen card to Rick! Watch the video again, and you can hear me giving the clues!

Well, there are two options.

First, you can time travel to 2045. Then buy "Rick Superb, the super-advanced voice recognizing Minifigure", who you can program to move with absolute precision. Program him to write numbers and symbols when he hears your secret codes! Obviously, this is what I did.

Or the second option, for those who can't time travel, will be to use Mindstorm and the new voice recognition plug-in and build a mechanism with four cross-shaped gears that each have 4 plates, which are placed into the space in the wall (figure 3).

You will need;

If I had Alexa, Mindstorm and the ability to code this, I'd definitely make it, and let Rick perform his trick to all my friends!

If you happen to have these abilities, please do make this idea real!!

This is my third entry to this contest. Please do check my other entries too.

They are "The Physical RPG" and "The Spell Chamber".
