My Famicom collection is now up to just shy of 400 different carts, more than 1/3 of the total released.
I set them all out in our extra room to take some pictures of them. These are a few of the shots I took (the lighting didn't work out too well on a lot of them):
I used to like to do this every once in a while because I think the carts look kind of cool when they are laid out like this. But I think the collection has gotten too big for me to do it anymore. A year ago when I had less than 100 it would only take about 5 minutes to lay them out so it was no problem. Now it takes more like an hour and its getting to be a pain! Plus the floorspace in our extra room isn't going to be big enough to fit many more of them:
