About a decade ago, my then-boss dragged me to a weeklong LabVIEW training course. The course was geared toward scientists and engineers (like my boss — I was sysadmin/programming/IT), and the instructor wanted people to bring data, problems, etc. from their own research to work on during the "hands-on" afternoons. I didn't have research, but I did notice that LabVIEW could open TCP sockets...
By the end of the week, I had written a barebones graphical MUA (e-mail client) that could read mail via POP3 and send via SMTP. "Written" entirely in LabVIEW. (The "code" was spaghetti – tons of boxes of all sizes and a rats nest of wires connecting everything together.)
The instructor asked for a copy to take back to NI, and I'd like to think that some NI engineers got a good laugh and/or vomit out of it.
