I stumbled across this while trying to figure out what my own symptoms were called. The right angles belying a wicked mess out of sight. Oh the things a two-year old can do that just tears at the fabric of all that is orderly and in place.
I couldn't believe the parallels between our "condition". Like you, I don't feel it is appropriate to call it OCD because OCD is a chronic life-altering thing. This is a definitely a more low level weirdness.
