One part that really caught my attention since getting back into Lego is the Bad Robot Arm
. It started as an arm for the robot minifigs in the 2006-2008 Exo-Force line, but the part has been repurposed in all sorts of interesting ways. To name just a few recent examples, it makes for the handle of a lawn mower in the Apple Tree House
set, alien limbs in the Galactic Titan
set, and even the toes and fingers of a monkey in a new Creator set
On one hand, I admire the creative uses the Lego set designers have found for this part -- as sort of a brilliant hack, repurposing something in ways never intended.
On the other, the perfectionist in me wonders why they haven't designed a more general-purpose shape for this piece. Its mechanical shape works well enough in some cases, but in others (particularly the alien and monkey) it seems a simpler shape with smooth sides would be a better fit. As often as they use this piece, I wonder why they haven't gone ahead and designed a successor. I know there's a cost to new molds, but they churn out new pieces quite frequently for the collectible mini figures and various sets.
Anyway, that's my Lego thought for the day.
