My friends didn't use capitals when sending me text messages, e-mails and using all their digital toys. At the beginning, I was feeling ignored. But after time I thought, that... I can do something for them.
And so, I've made Redaktor. Redaktor is a cute monospaced family of four fonts, which has only lowercase characters and large x-height. If you want to write an uppercase character, you can't do it. (OK, to be fair, there will be small underline, just to show you, what you have done...)
You may find Redaktor useful for posters, titling, info-graphics or websites.
