DolphinSmalltalk

Is anyone using Dolphin in production?

Yes, a number of people (that we know of). The Zagreb Stock Exchange uses Dolphin clients and a Smalltalk/X orb. There are some medical information systems (US and Japan) and a petrochemical distribution system using 3D graphics amongst others. However, perhaps most importantly :-) you can drive LEGO with it:

Best thing to find out more would be to contact the Dolphin newsgroup comp.lang.smalltalk.dolphin.
