I was a phone phreak, and I still have my last old-school brown Radio Shack tone dialer which I'd been planning to make into a red box. Ultimately I was too lazy to swap the crystal in it, and it sat in my junk drawer for years while red boxing died. Now it's a curiosity that sits on my shelf of hacker books. Maybe I'll still do the crystal swap someday for the sheer hell of it.
Most of the feet posts online aren't my thing personally, but I must admit there's something to this.
