Couldn't you in theory build a clock purely from nand gates? You create a cycle of nand gates where the output of one is tied to both inputs of the next. If the cycle have an uneven number of nand gates, each nand will oscillate with a period depending on the length of the cycle.

You can use NAND to make NOT.

That's quite unexpected. Thanks.

If that's unexpected then I really find it hard to take your earlier comments serious.
