I wanted it all to be pixelated but drawing the towers from scratch would be time consuming and I went video/screenshot hunting for anyone that had built the Twin Towers in Minecraft.
The quality of Samurai Shodown's Houmaru was thanks to having, by chance, my M.A.M.E. emulator handy and grabbing screenshots from the iconic (at least to me) game introduction. I remember him slicing up two lamp posts being one of my favorite things ever, second only to Super Street Fighter II's Ryu hadouken intro sequence. So the concept was there, but the art was going to suffer because I wanted to post SOMETHING on 9/11. In the end, I wasn't satisfied but I bowed to set things right by fixing what I could AND making it animated.
