Try LCDs instead of CRTs. You can watch TV on them as well. No flicker. In my office, I use a lamp stand that directs the light to the ceiling and then it's reflected down. Those are fluorescent bulbs and casting them off a surface seems to help a bit. They do this in some buildings instead of aiming the long bulbs directly down on your desk. If it hits different surfaces and has a diffuser it doesn't "seem" to flicker as much.
