Move Points along normal HOUDINI

peak SOP is your friend.  It transforms the point along the point N, or you can use a point SOP and do a $TX + ($NX * 0.1),  $TY + ($NY * 0.1),  $TZ + ($NZ * 0.1) in the position paramter.  The 0.1 value is the amount you want to move it along the normal.  That expression is doing what the peak SOP does.
