    Biogenesis Color Mod

    Mod for evolution simulation and artificial life program Biogenesis

    You can download the Color Mod at the Biogenesis main site too (included in the main download now). You also find the sourcecode there. If you want to post a review, remember that this is only a modification, so comment on my changes, not on the simulation. Original project by Joan Queralt Molina: https://sourceforge.net/projects/biogenesis/ Includes Tyler Colemans "Features Mod": https://sourceforge.net/projects/biogenesisfeatu/ Biogenesis discussion forum: https://sourceforge.net/p/biogenesis/discussion/ Biogenesis runs faster (at least for myself) if you open a Google Chrome window (don´t know why :D)
