@tudoreleuu(View Post) What if there is a completely inert element that you could place wall ontop of without being destroyed? That way you can color the element.
@plead-for-destruction(View Post) On a message board, posting something irrelevent on a really old topic to bring it to the top of the list topics. name comes from the fact that you are bringing it back from the dead, thus Necro. a practice common among http://www.urbandictionary.com/define.php?term=necroposting "Necroposting" (also called "necrobumping" or "gravedigging"), occurs when a forum thread that has been inactive for a long time, typically years, is bumped by a reader, usually in response to what he inadvertently believes to be an ongoing discussion, perhaps coming from a web search rather than from within the forum. http://en.wikipedia.org/wiki/Bump_%28Internet%29#Necrobumps
"Deco" for walls would be such as every wall block has a single colour, making CELLxCELL squares of colour. (Currently CELL = 4 )
