I’m planning on being there the whole time (give or take a little time to check out the other displays).
Getting more into MOCs – I keep forgetting that my “old crap everyone’s seen already” hasn’t really been seen by everyone already. I’m still really behind on current photos, but a friend of mine got overview shots of most of my island at BrickUniverse Raleigh this year: https://www.flickr.com/photos/black-six/albums/72157667117408541 – there were a few other contributions to the “Mini Con” display there, but the rest of the MOCs there are mine.
In there, my interactive items are my pneumatic walker: https://www.flickr.com/photos/black-six/25868502373/in/album-72157667117408541/ (the kids use the hand pump to run it) and my DUPLO Ball Run: https://www.flickr.com/photos/black-six/26405190081/in/album-72157667117408541/ and https://www.flickr.com/photos/black-six/26379018602/in/album-72157667117408541/ (the kids take balls from the end and put them in the start). The pneumatic tubing for the walker has worn out and keeps popping off, so I’ve ordered some off-brand tubing from Amazon that should work better (it might be in before I leave on Friday). I build the ball run differently every time (most of it has to be built on site), and I know a few of the modules from that event (last April) have been rebuilt differently or scrapped entirely already. I usually set that up to sprawl across/in front of 2+ tables, though, and having the ball run and the walker on a table tends to encourage the kids to lean against/shake that table a bit more – so they might not be a good idea if we’ve only got one table of MOCs.
The building that folds up is the pink one from this photo: https://www.flickr.com/photos/black-six/25868502643/in/album-72157667117408541/ – I think the other items there are fairly self-explanatory. Most of it’s available again if we want to have it out (except for the Star Wars scene and Piranha Plant, which need too many repairs).
