The lego bricks used in the mod featured in this blog are red, not pink...and I was not the fist to combine a USB Flash Drive and Lego bricks as you can see here.
I used red in the first place because that is the color that comes to mind when thinking of an average lego brick, and it is the color of brick used in Lego logos, labels, etc.
I suppose if I were to do a version in a yellow color, it would be called piss.
So I think another version will use blue just to be safe....unless there is some other color that is worse and could be confused with.
Once again, the bricks are red, not pink.
not this color
