On the 19th of feb 2007, around the same time bErNaX did his tank (i think), i did mine like this. I know there is no proof etc etc but I dont feel a need to justify myself on who did this first.
Lol. bErNaX, when I saw your hardscape, I got the scare of my life. Its so similar! I decided to change mine a little and let you have yours. You post it up faster then me
plus urs looks way more developed. good job!
