Random thought #1. "Come again? You drag-drop an actual image into the search and look for what's similar? Whoa, shit gets interesting!" Yeah. I didn't know that.
Random thought#2. "Ahh, these date-specific results won't show up unless I pick the specific medium. I would have totally missed that on my own."
Random thought#3. "Translation activity, lessee... "Please find the answer this question: Apa warna pada bendera Indonesia?" Well, it's a question alright, so the first word's probably the 'ask-word' (that's literal-translation from Estonian for whatever the official term is); Indonesia obviously stands for Indonesia; and "bendera" - that's your typical Indo-European-ish for "flag"." In other words - I totally cheated : I bypassed the search tools that I was supposed to be practicing and just guessed the question instead, then checked out Indonesian flag from Wikipedia.
But here's my own little quiz thingie (just came up with it all by myself). Here are three flags. (Thank you, flags.net.) One of them is the answer to Google's activity, one of them is of my home town and one of them is another country. So, guess and stuff. (Or don't.)
