Made this for my nephew's 30th birthday party. Lego pieces are modeling chocolate with individually cut and applied dots...lots and lots of dots. :) Cake is supported by 6" acrylic tubes I found at a craft store (meant for centerpieces, I think). The thrusters in the rear view are made of gumpaste using a silicone tire mold with blue LED balloon lights inserted.

I'm a home baker, and this is by far my most complicated cake ever. Truly a labor of love.
