As there was pretty much a unanimous result on that poll, here's my very rough guide to drawing Sonic style spikes.
I tried to cover the basics, but you're gonna have to work a little to get other angles as I couldn't figure out how to describe them. If you need more help, feel free to ask and I'll try my best to answer ^_^;
Hope this helps a little anyway!Just remember, I tend to cheat when I draw them. A lot. Might show you that sometime
Edit: made a quick adjustment to the Super Sonic note: that center bottom spike is down to interpretation, sometimes in game you see it down, which is how I draw it, but usually it can be seen up, so do it how you want
