There was a large set at SciTech in the main exhibition on our last trip and Tao made a wearable R2-D2. It was the first time I've seen it in action and I've since acquisitioned a few sets of 3 as group presents for friends' kids.
One of my automatic go-tos at least every Silly Season, if I'm organised enough I'll occasionally poke in to organise a birthday present as well. Beautiful and quality stuff (a Green Toys tea set that I bought for Ru a couple of years or so ago got taken outside so they could have tea party with water and then got left outside since is still looking in very good nick, could probably scrub it up and have it looking more or less new) that gets played with constantly because it looks good and doesn't break when you look at it. Just wish I had more money.
Okay so this one was Josh's department because he has the eBay account. I told him what to get and he got it (plus a few more things because he spoils the kids but not as much as the grandparents).
For the people who have everything and those who don't.
Happy Silly Season :)
