My first enconunter? It was short after I graduated high school and started studying medicine, so 1992 or '93. Me and my friends from high school visited computer fair Infosystem in our city (Poznan, Poland) where I saw teal Indigo2 with some kind of cad software, guy in front of this played (rather then worked) with full screen, fully shaded model of ship propeller, I remember it was moving and rotating so smooth.
Second time it was during medical studies, on gynecological ward, they showed us brachyterapy system (for short range radiotherapy in women's cancers), crucial part of it was IRIS Indigo (Entry I suppose) which was simulating spread of applicated dose of isotope and calculating needed dose and target for depostion.
