I've had a few beers, i'm lacking sleep, and when i cast my eye around this pattern of cheques/checks (what is the correct spelling for that?) the grid lines appear to wobble. Is it just me? or have i stumbled upon a common optical/psychological illusion.
hmmm i forgot to add the picture.... funny huh?....nah not really.
It's not really working for me now, I think seabreeze broke it.
I think it might have! as there is no wobble for me
but dam..it give's me an eye ache looking at it 
After a few (too many) beers my foot starts to wobble, damn Blundstone wobbly boots do it to me all the time.
