Those are bad ass, especially the flip flop. I would have gotten a better grades in Electrical Engineering if I had these puppies.

Yeah these were all the rage at work today (if 2 programmers asking me if I saw them constitutes a rage). What comes after flip flops? Adders?

For some reason i keep getting "connection refused" when i try to click the link. Could be my shady internet connection

After flip flops you can make registers (cascaded flip flops) or really any type of sequential circuit. An adder is asnychronous, you can make them with and gates and xor gates.

6 years of EE finally put to use! Huzzah! :)
