oh wow, I was just playing with all the dialtone frequencies in a little ios app:

I really miss those sounds. Learned so much about all the different frequencies. No to get too woo-woo but did you know each tone is actually two frequencies a high and low one?

The video above shows dialing either LOVE or FEAR. Not sure where this app is going but I had this idea to help catch myself whenever I'm following fear vs love.
