I might be able to volunteer for this role - While my Python is a bit rusty these days, I have a good understanding of OOP and event models - i spend most of my programming time working with the flash AS3 language (Similar to JAVA in it's structure.). That is to say, i could do your UI, but it would take a little while, as it would, of course (Presumably like everybody here?), be only in my spare time.
So yes, i'd like to have a go, more details on exactly what is needed would be useful - as well as direction towards the applicable reading material for project or engine-specific information i will need. Do you actually have some sort of cunning plan regarding exactly what you need?
Thanks!
