Thanks, geeker. And, yes, chrise, this was simpler than most prize crosswords but 2D, even though I have all the crossers, know what the anagram is, and know the ending, thanks to jazzgirl, continues to elude me. I've plugged in several variations into Google and got nothing so I guess if I just kept on going I'd get it eventually but instead I'm just going to forget it and wait for the solution to be published.
So, if 2D is just another Wikipedia lookup clue then what's the point? I'd rather the solutions be reasonably well-known words in the English language that are craftily clued than anagrams that you plug into a website. Where's the challenge in that?
