Bipolar Current Source

I'm looking for a current source like the one suggested in CN0099 http://www.analog.com/en/circuits-from-the-lab/cn0099/vc.html.

... but bipolar.

Unfortunately, that circuit doesn't work with negative reference voltages.

 

My goal is to achieve a current output range varying from -10mA to +10 mA, with R1 = 500 Ohm.

 

Any suggestion?
