How about writing an entire laboratory software program in Access and Access VBA! lol. That is what my partner and I are doing. We started working on it last October knowing NOTHING about Access or VB/VBA - what a trip! I have to say it's been a lot of fun, not mention EXTREMELY educational! Our lab is now using our project exclusively for their data  entry and the project continues to grow and expand. In fact this week another area of the lab is beginning their move to our system.
