Erratic Patterns

Look at the pattern, can you see what's wrong?

It's supposed to be perfect, but really it's not.

Can you find the flaws, hidden in structured code,

Hiding in the pattern, In between the rows.

Now that you know, that something's not right,

Look at it carefully, in pale logic light.

Don't be sorry, if you can't recognise

The errors and faults, in such a perfect disguise.

Only illogics can find hidden flaws in a straight logic line.

Only erratics recognise errors in patterns of a perfect design.
