Beating Heart

I made this good looking beating heart (.. Accidently invented near the valentines day. ;)).The device has 20 LED`S that blink at a hardware specified rate. Unlike the conventional approach of using micro-controllers i though using a simple 555 Timer would be great ..adding to it ..it would simplify the design and make it less cuber-some for those who either have no prior knowledge or dont want to waste time gathering the same.
Here`s the thing you might get after going thru the rest of the instructable.

Step 1 Getting the supplies

Things that are required:
1 x NE555 Timer 
2 x 10k Resistances
1 x 100uF Electrolytic Capacitor (25V)
1 x 10uF Electrolytic Capacitor (25V)
1 x 9V Battery / 3 x CR2032 Li-ion
1 x Through hole board
1 x 9V Battery connector
1 x  IC Base (8 pin)
1 x  Push Switch ( to avoid ur heart beats in front of everyone:D)
20 x  "identical" Red LED ( Identical is the catch in here.. as if they are sourced differently u might end up having uneven brightness..which will be disappointing) 
Wires as required..( it goes to like " Salt to taste")\
And lastly  "Spare Time"

Other Things that might be available at hobbyists are:
soldering Iron, Solder, Flux, Tweezers, wire cutters, Helping Hands ( Clamp tool)and hot glue gun.

I guess a 555 timer Ic is the most awesome IC ever invented. I will make this

This is cool. If you want to get a better heartbeat, make this circuit instead. It is supposed to be like a bomb but if you substitute the LEDs for the speaker, it will look much cooler.
