Interesting Connections

Here are some interesting Lego model connections. Enjoy!

I think that this could be used as very solid bumper because of its flat front. I learned from this that two half plates together makes a more solid surface than one plate. 

This is a very strong base connection for a model. I learned from this that awkward pieces can be used just as well as average, everyday pieces.

This connection looks like a scorpion's tail and because of that, be used for connecting a Lego Mindstorms (Look it up!) light sensor upside down on it. I learned from this that can serve more and more functions the more you stare at it.
