Yes, the physiology and "gengineering" are daunting, and probably impossible under any circumstances for animals of our size. Yet those who bear wings under recognizably this-worldly conditions awaken my own spirit, as if the brush of their feathers lead to a metaphorical freedom that I can touch ... and that is almost too far away, in most ways, in the world we must deal with each day.
The untitled painting at the top of this comment, with pencils by George Pérez and colors by Nei Ruffino, will appear on the cover to Final Crisis: Legion of Three Worlds, issue 5, due in March 2009. It features a favorite character of mine, Dawnstar of DC Comics' 31st-Century Legion of Super-Heroes.
In addition to the links above, I have available for those interested:
~ A Yahoo! Group for pteraphiles ("wing-lovers"), with a mailing list and visual and prose collections. ~ A YouTube video slideshow of many of my favorite winged works (and some showing "me," Greybird, Dawnstar's brother) out of my collection of thousands. ~ Two more static galleries of visual winged favorites, one about Dawnstar and one more generally, with yet more links, at my ComicSpace page. ~ A personal page at deviantART with some of my prose, along with links under "News" to showcases of more winged art at that huge site.
I'll close with another special favorite, linked directly: Boris Vallejo's "Showing Her the Way." We should all aspire to feeling and being this free in guiding the coming generations.
