not that hard actually if you have working knowledge of any 3d program
you pick your fonts, type out the word in 3d then any additional shapes can be made out of primitives and curves. The finishing is just slapping a lensflare on in photoshop. Shouldn't take more than an hour to pump out.
side-note to the creator:
I'd reccomend going for not-so-recognizable fonts by the way, especially avoid fonts already used by things like bands & movie titles.
1st submission has the font that looks like the font in Blade Runner but i am not so sure on that..., 2nd submission appears to be using the Kiss font.
