Engineering workshop : What's the top 10 recipe of a true Engineer Master ?

Hi guys. At the end of WoD, I choosed to please myself with a new fun toon and a new profesion. So I made an engineer Monk. I know that Legion is not the best time to be an engineer but once you've tasted the glider and the nitro boost, you cannot go back!

As a good apprentice, I made a jeeves and unlocked the tinker stuff but I've also disvovered that there is many many fun little old goodies and recipe out there.

So I was wondering : What is the top ten recipe of a true engineer master? It doesn't need to be usefull or anything, just fun as hell or simply vanity stuff.

Tell me O master!
