Lazyweb: NUMB3RS and whiteboard markers

Lazyweb, I’d like to know what dry erase markers are used in NBC’s hit drama “NUMB3RS”. Despite my best TiVo-rewind efforts, I can’t make out the brand and type of markers used. Most often they are a bright yellow ink that shows up very clearly on clear glass as opposed to traditional white boards. What are they, and can I get them?

Bonus points: Can anybody confirm the pen used by the Architect in Matrix: Reloaded? I believe it was by Lamy, but I want to be sure.
