On: Expired patent of the day: Lego

[utunga]

interesting how, when first invented, the bumps went down

kinda makes more sense to have the top side flat - but just feels so wrong to me now.... interesting

Isn't that just a matter of how you hold the brick?!

[ErrantX → utunga]

Just a theory; but it is possible the isometric connected bricks are depicted that way up so that you can see how it interlocks a little better.

(although, that doesn't explain the 2D versions that are "upside down")

Where did you get that idea? The picture shown has the bumps on top.
