I actually used to do this - just have it casually sitting on the side of my desk. Most of the time it was lid-open off to the side (which ostensibly signaled I wasn't actively working on it, maybe just checking something). In rare cases my manager came around, I could pretend quickly enough I was actually working. This ended up being a very productive period for me personally (maybe 3-6 months) due to this change.
