Yes, I have seriously tried it. Maybe it works for some people. It's of course quite hard to recall why you really remember something, but in the 800 kanji I know according to the test, the vast majority I seemed to remember from seeing/using them in context while reading/writing Japanese. Mnemonics are an attractive thought, and I hope they do really work for some people. Personally I am a bit skeptical. My feeling now is that learning doesn't have to be brought up to conscious thought, but is something that happens naturally as you re-encounter things. http://en.wikipedia.org/wiki/Spaced_repetition
If you'd like, you can combine these two things too. http://kanji.koohii.com/learnmore.php
