@Mainer35, I see you asked about tets! Here I am being an ambassador for dips. Reminds me of being in school and not reading the test instructions thoroughly... and particularly like that trick test that we got once where it told us at the top of the test instructions to read the whole thing before starting, and then the very last instruction was to only do something tiny, like put your name on the page. And all the students who hadn't gotten the clue were working away for ages at the many questions. So the instruction-readers were watching the impulsive ones work, and feeling smug. Strangely, I don't remember which of the two groups I was in. Maybe I was in-between. Saw something was going on and figured it out? It's been a while...
And I imagine Judy Davisson's marvelous purples might do well up there, if you can get your hands on them.
