Cristina, my girlfriend, had come to Denmark. Therefore, I wasn't able to do any new work on IsohexEngine :)
She will return to Romania on 29th May, but then I will be entering my last week in Denmark and have to start to prepare for my own return.
This means that development will stall a little these next weeks. But don't worry, I will not abandon it :)
As a side note, just before Cristina arrived, I have started looking into Guichan and how it can integrate in my current framework. The good news is that it can be done and this will be my next top priority: get some simple UI for the current renderer demo application.
