nope.
Yes, my design had no flap.
Isn't it funny - we are challenged to come up with something better, and when we do, it is laughed or denied away.
Had a YEC engineer 'challenge' me to design an eye that did not have a blind spot (because an eye with a blind spot is the BEST!!).
Piece of cake - I posited that the axons of the photoreceptors and ganglion cells in the retina could be directed to the periphery of the retina, routed behind it, to converge centrally to form the optic nerve. Voila ! No blind spot.
He called me "stupid" because this would create 'shadows' on the retina. I explained that if shadows were an issue, they would be worse with the current design since as they converge toward a central location, they start to overlap each other (think the spokes on a bike wheel). Nope. I was wrong.
Even though I wasn't. Such is discussing anatomy with non-anatomist creationists.
Oh, forgot - he also claimed that it is impossible for gases heavier than air (Like CFCs) contribute to climate change because they would not rise - and to prove this, he explained that if you put a drop of mercury in a glass of water, it just sits there. I explained to him that if he was right, then we would all be dead since there is enough Argon (heavier than oxygen) in the atmosphere to form a layer at the surface of the earth some 60 feet thick (or whatever it was - this was a long time ago).
As this was on his Google group, he just banned me....
