New Things to Mod
Well, I was thinking that there's always something to mod. There's always a new craze, like flash drives, camera lenses, anything. But I'm pretty sure this is new: custom matchbox cars. The ones below are a few examples. You can spray paint them and then do touch-ups with acrylics. For more advanced modders, you could try to integrate shocks and stuff. I will post an instructable on this if you want.
I think that modding is a necessary part of instructables and we always need more ideas.
