I have been trying to do this for last couple of months. There are negatives (such as a bit of lack of attention) and as well positives (I can keep bottom at one place for a little longer).
I was wondering is there anything else you do along with coding?
listening music?
This provides something to look at to distract me for a short time (helps me to get ideas popping back into my mind) and just generally provides some background noise.
