Star-like Object in Rapid Non-Linear Motion

Currently observing a mysterious light source beyond the distant Northeast sky.  At first, I assumed it to be a sparkling star, or far away plane, but then its motion demanded more critical attention.  It moves at a constant and seemingly unpurposeful rate and direction, resembling the actions of an insect (sometimes fast, sometimes slowly, back and forth, and in circles).  Less frequently, minute alterations in the light distribution suggest multiple aspects but these are fleeting.  The colors are indistinguishable yet alternating.  It looks mostly white.  It has not crossed a significant amount of sky span from this perspective, yet it seems very very far away.  Its speed and fluidity is phenomenal!  It does not grow nor reduce, and the light reflected by it flickers.  It is mesmerizing!  Ongoing, 30 mins since being noticed.
