Hi,
I would suggest you to use the Forest Pack plug-in for these purposes as it allows you to drive the rotation easily by the Transform - Rotation - Map (in the attached sample scene by a procedural Gradient Ramp map, which can be replaced by your Bitmap map / any map which will suit best your needs). To create the running bond pattern, I've made a copy of the Forest object with adjusted Distribution Map - Offset X & Offset Y values. Attaching a sample scene, hope you'll find it useful.
Best regards,
