minty heart going wild with contact sensor

This is not an original idea, two weeks ago i found the minty Beating Valentines Heart, where i begin, this is a little remodelated instructable i have mounted to gave a very special friend, My contribution is the acelerated beating rate depending on the parallel resistance of the skin.
I include photos and schemes to help me describe the assembly. This is a very simple circuit, like you will see.
PD: I also include an origami beating heart, from here

Step 1 Parts

You will need a few electronic parts and some waste materials.

1x 555 timer
1x 27kOhm resistor
1x 3,3MOhm resistor
1x 470nF condensador
2x AAA batt
thin cable (like USB data cable)
some connector
soldering iron
Lead solder
Adhesive tape.
1x CD Lens (with coil)

Let's go with the circuit

Thank you! I'm sorry didn't post it before 14 February, i would like but I had a lot of examen before today. Respect 14 february I did a bad job too :) Another thing: This is my first publicated Instructable! So I invite all people to tell what can I improve. The first thing would be my English? jajaja

Hey boj, Three things: first, on the desktop, in Spanish, does it say "time to lose" and if so why... also your "jajaja" could be translated to hahaha or you could keep it as jajaja to show that you are a spanish speaker. Its cool that your working on English. Where are you located?

jajaja, I mean, hahaha. Thanks for clarify this. I'm in Spain. I 've worked in English because Instructable talks English.
