Stupid engineer...just draw the thing in an 11-dimensional space, and he would h...

My comment when someone posted this on Facebook earlier today-

"Although... A true engineer would know how to solve the problem of 7 perpendicular lines. And a master corporate engineer would get the budget for developing 7 perpendicular lines. Actually, that more or less explains defense contractors"

Perhaps I'm not thinking clearly - it's late here - but wouldn't 8-space suffice?

A 7-dimensional space would suffice to fit 7 orthogonal directions---though we should probably add an extra dimension for the alpha channel ;)

BTW, I'm also guessing @lam's comment was referring to the 11 dimensions in string theory: http://en.wikipedia.org/wiki/String_theory#Extra_dimensions

Also, throw in some velocity dimensions so that we can make the red lines drawn in green ink appear to be red.

7 dimensions is the trivial minimum for 7 mutual |_ (the axis)

Also, if you ease the restriction to each line perpendicular to every line it intercepts, you can get as many lines as you want in 3d already.

That works in 2d space, too. Parallel lines don't intercept any more than skew lines.

Really, he should draw the first three dimensions of red lines in transparent ink, and the higher-dimentional ones we cannot perceive in green ink.
