Mine is minor compared with some of these - at last I have finished my "homework" for the zoo class I go to, the deadline is tomorrow. We'd to pick an enclosure we thought need upgrading and redesign it. We could work in groups, so a friend and I joined forces.
It involved research into the needs of the animals, the keepers, and the visitors, and a look at what other places were doing. Then it took a bit of artistic effort to alter photos of "as is" to "as it could be" which meant I'd to learn how to use photoshop. Steep learning curve. Eyes bleary from excess computeritis.
If anyone has missed my pearls of wisdom the last couple of weeks, that is where I have been. Now I just hope the presentation goes OK.
