Title: An order/disorder perturbation of percolation model. 
A highroad to Cardy's formula.
	
Abstract: 
We will discuss the percolation model on the hexagonal grid. 
In 2001 S. Smirnov proved conformal invariance of its scaling limit 
through the use of a very specific observable constructed in a 
combinatorial way.
We will see that this observable is clearly visible in the order/disorder 
perturbation of the model. This observation brings new results and a 
slight hope that one can generalize the proof for other lattices.
No specific background is required.
