oct22a_2011 is small practice. The particles, which form this grid, can dodge your mouse track, while the grid is generated by Lee Byron's Mesh Lib. You may press "r" to reset the position of each point. The algorithm for the movement of each particle is the same as my former "Colloid Text". Hope you like it : )
