Sorry for the late response, been offline. Thank you for that red/blue homage. I've always been intrigued by the optical tricks that contrasting red and blue play on the eyes. That little series was my exploration of those colors- I wasn't super happy with the effects, but oh well.

Regarding the mirror panel thing, I will usually modify the mirror slightly as I did here; ...gridcosm?level=985 Don't know how rewarding it is but at least I tried . . .

Pretty much agree with Sunny's scrabble metaphor- it can be useful when faced with a complex square. If you don't change anything, why bother?
