So after proposing to my girlfriend at TFcon we're starting to plan things for the wedding and intend to incorporate some transformers stuff into the reception. One of these things is that we want to setup a particularly difficult transformer at the reception and whoever manages to transform it properly without instructions will win a bottle of booze.
This is where you all come in. We'd like your input on what the hardest transformer to transform is, with the caveat that it's not insanely hard to find/prohibitively expensive. Most of these people aren't going to be accustomed to handling transformers so also try to keep that in mind and shy away from something that someone might easily accidentally break.
Your input on this is greatly appreciated, thanks.
