My active personal projects crystalize around two main topics:

calendarium-romanum
Ruby gem aspiring to become the most complete FOSS implementation of the Roman Catholic liturgical calendar.
Church Calendar API
Public calendar API built on top of calendarium-romanum. Makes results computed by calendarium-romanum available to applications written in languages other than Ruby.

In adiutorium :: http://www.inadiutorium.cz
Web presentation of my musical settings of the Catholic Divine Office in Czech translation + comprehensive catalogue of other existing musical settings.
E-Antiphonal
Web application proxying another web (Czech Liturgy of the Hours on-line) and extending it's content with my musical settings of the rendered texts - thus turning a "breviary" in an "antiphonal".
gly
My custom language for encoding of gregorian chant + it's translator to gabc (a de facto standard language for the same purpose, but not very user-friendly).
grely
Translates gabc scores to Lilypond. Leverages a PEG parser of gabc.
pslm
Automates pointing of psalm texts for various chant tunes.

Budebylo
A small events calendar application for a local scouts' group in Kladno. (1 page of public frontend + administration interface; PHP+MySQL; in use since 2008; non-free, closed-source)
freeVikings
Attempt to make a free clone of the famous Lost Vikings. Developed 2004-2009.

A bit of vanity: here might be the oldest (or at least the oldest publicly available) bit of Ruby code written in the Czech Republic. If you happen to know an older one, please e-mail me.
