Here's the problem: How to sequence them? The guys at Radio Shack had NO
advice at all -- they were all stumped.

The guys at most radio shacks these days can't change the batteries in a
flashlight without a training video and a map.

25 years ago, I would have grabbed a 555 timer, a 4-bit counter, and a
4-to-16 demux out of my TTL collection and built a sequencer in an
afternoon for about $10 in parts. The breadboard it was built on would
have cost more than the chips. Of course, if I told you I was going to
use it to drive a series of blue LED's, you'd look at me like I was nuts
(everybody in those days knew it was theoretically impossible to build a
blue LED).

I wish I knew were all that stuff went. I can only guess it got tossed
when mom sold the house a few years back.
