My Calculus class had an ornament contest. The night before we voted, I was finally struck with inspiration and made a festive Sigma out of LEGOs. 'Twas the only LEGO ornament present, and it ended up winning!
Thank goodness for PAB; without it, I would've never bagged those trans-cones in bulk!
Inner workings, I guess. Those technic hinges saved the day, allowing me to achieve the weird angles a sigma has.
And finally, it actually attaches to the tree! It dwarfs all the other ornaments, but I like it that way :)
Hopefully, I will make and post a couple more festive MOCs. In the works are decorating the Santa's Train set, and fashioning a special ride for ol' Saint Nick himself!
