An example how fast technology has advanced, I'll quote from an article from the May 12, 1996 "Sunday" magazine (Plain Dealer):
"When a crane lifted the last piece of track [on MANTIS], a piece of paper would not fit between the joints. By way of contrast, there was a foot gap between the final two pieces of track on the MAGNUM XL-200."
It's been four years since then- MF probably went together easier than a K'nex set.
