cool! good one. i was planning to get a photo of octopus for today. got to go to chinatown there's always some displayed in restaurant windows. hope luck's on my side!
Onion, olive, oil, (or olive oil if you prefer), okra (do you cook with that? I don't!), on, off, over, oven, open, oscillate, oval and out. Looks like you could get a whole month's worth of suggestions just by telling us to give you some ideas! LOL I like your octave!
