In my psychological research I use a multilingual electronic dictionary named Lingvo version 11 (developed by ABBYY) for translating my graduate thesis paper into English, because my department of the international University I study at does not accept papers in German.
My special idea is creating a universal dictionary of psychological terms and definitions and selling it to ABBYY. Then it would be translated in 6 languages available - Spanish, English, German, French, Italian, and Russian, and integrated into Lingvo package. International students and doctors of Psychology, Social Psychology and Brain Physiology, psychology amateurs as well as translators would be really eager to pay good money for such a dictionary!
I think I'll start developing it after I complete my research and succesfully defend my thesis.
