While at the Qld Astrofest, I was impressed with some of the clever innovations people came up with to make observing that little bit easier

. In particular, I saw some very clever designs for portable tables and "desks" to hold charts and miscellaneous bits & pieces while observing.
Unfortunately, I wasn't clever enough to take photos of them to give me some ideas from which to start making my own

. So I was hoping I could talk some of you fine folk into posting pictures of what you've done for your observing desks and tables.
Anyone have some good ideas they'd like to share?
