Wittro, which mean "Wittemberg Intro" was completely done during a weekend spent in Wittenberg/Germany on Spectrology 2013. Factor6 started to do a small basic demo and I've got an idea to make propper asm dentro. All the gfx, music and code was done on meeting place, but we took another 2 days to polish gfx (still crappy anyway) and music. I found out that I am really not a realtime coder, it took me too much of time and the reslts are probably not worth of it. But I like the possibilities of this easy effect and will try to get more of it in some future product. Just few colours and proper pattern changes.
