Not a black hole

Eventhough Jacco had clearly pointed out the danger to me, it nearly went wrong. In the floor underneath the table we were working on there was this big hole. It was created to allow for some cables to run through, but was also more than big enough for one of the legs of my chair...

[ and you're not very stable on a chair with only three legs... ]

Watch out: Chair leg swallowing hole...

Luckily the carpet around the hole was very bright and cheerful, making the hole less scary than it really was...
