LOL! OK, where's my latest Insight spam... OK, Autodesk AutoCAD LT 2010, 


I'm *so* not trying that. :-P

Yeah, well, you make small hot things, right? ;-)

I was chatting to some guy who apparently designs bridges and so forth. 
Maybe not "bridges" as such, but things like motorway flyovers, ramps, 
etc. Apparently it's kind of important to know about such things...

Personally, I know very little about this kind of thing. Although I did 
read somewhere that at high speeds, materials behave as if they are 
harder and more brittle than they are. Which would explain why jumping 
belly-first into a pool of soft, liquid water is so God-damned painful. o_O
