Hi all, long-time lurker, first time poster here.
Got a bit bored this week, wanted to try a few eye-deas I'd had.
First thing I looked into was an Eatock design based on the Egyptian "Eye of Horus" (I reckon this spouted from my love of Only Connect). This was the end product.
Then I was trying to come up with some decent change to the C5 eye, which proved kind of difficult. I had a Ying-Yang idea, but I lost that eye, so I looked into putting the Symbol of Mars & Symbol of Venus onto it, which has the same "Male/Female" vibe a Ying-Yang would, here's what I ended up with.
