The Expert

PHB: "That's it. Now you've confused everyone. So what exactly is stopping us from doing this?"

Anderson the Engineer: "Geometry."

Client: "Just ignore it."

PHB: "We have a task. Seven red lines. It's not 20. It's just seven! Anderson I understand you're a specialist of a narrow field; you don't see the overall picture. But surely it's not a difficult task to draw some seven lines."

Walter the PM: "Exactly! Suggest a solution. Now, any fool can criticize --no offense-- but, you're an expert. You should know better."

It's a shame that this will die in "new" submissions. Because it's fuckin' hilarious.

Solution:

Use red paper.

Draw the straight lines in parallel to one another then fold the paper diagonally so all lines cross all lines.

Draw the transparent lines with transparent ink (e.g. an ink corrector pen).

Using a green pen draw long thin boxes; i.e. outline of the resulting red lines.

Kittens / birds: have it in the shape of a kitten or bird approaching a blackhole (spaghettification) - or draw in a straight line whilst moving the paper to create the shape / do some really creative folding.

Kitten Balloon - put the deflated balloon into a (small) kitten shaped mould and blow it up in there (leaving it in) - or pose as a kitten whilst inflating the balloon (so you're inflating it in the shape of a kitten, rather than the inflated balloon being in the shape of a kitten).

Or... Based on Randall Munroe's strip http://xkcd.com/1351/, an even better solution to the ink colour problem.
