This rocks. A hit with any math teacher or professor.
The link provided no longer carries this item. I want 4 of them. Any other information about where to get one? Ebay has one with bidding at $36 right now. I am not going that high.
Sorry, I haven't seen it elsewhere. Good luck in your search, though!
The Signals catalog (or online store) carries this item.
