Tell us how you made it

Looks good.

 

[MrMcChicken]

I will make a short tutorial tomorrow ^^

 

[Guyfromhe]

Sweet.. Looking forward to reading it.. Maybe I will give it a shot if it doesn't require unobtainium.

Geez, it's been a loooong time since chemistry classes...isn't the periodic symbol for unobtainium = Uo.
And the number is some unrepeating infinite decimal ?

Makes me want to divide by zero and end it all !

 

[Guyfromhe]

Could be.. Anyway the stuff is impossible to get!
