Project: Logos Hope Visitor Deck - Mini Game

Logos Hope's deck revamp will feature 1-2 min touch games. "Clean the Water!" is a pipe puzzle (3 modes) where players filter polluted water for sad children. Successful play leads to a 30s video and contactless donation prompt. #HolyHack goal: design gameplay, optimize donation, and build a POC.

Project: Python tool for 4training.net

4training.net is the international sister site of trainingfuertrainer.de. It offers copyright-free discipleship worksheets that are translated into many languages on a voluntary basis. The goal is to develop a Python script (with Mediawiki API) to simplify the translation process. The script should copy finished worksheets from the staging instance to the live instance by command and thus facilitate the work of the translators. Project scope: 2-5 hours.

Project: trainingfuertrainer.de Relaunch

trainingfuertrainer.de trains disciples of Jesus. To promote multiplication, all materials are CC0 (without copyright). The website urgently needs a relaunch: clearer design, better communication of the vision and orderability of the "Books 2.0". The aim of the HolyHack is to realise this improved homepage, including a call for cooperation/donations for the non-profit association.
