I frequently drive through Brancepeth on my way to Low Barns and recently I’ve been watching with fascination the unfolding drama of this bracket fungus. This is Dryad’s Saddle (Polyporus squamosus), also known as Pheasant’s Back Mushroom, presumably due to the distinctive surface of the top of the fungus that you can’t see in this photo. It’s fruiting from a pruning wound on a sycamore tree (Acer pseudoplatanus) next to the main road in Brancepeth.
I’m passing this tree and fungus almost daily and watching with wonder to see if it’s just going to get bigger and bigger. Who knows, one morning I may drive by and discover it’s gone. Disappearing as suddenly and mysteriously as it arrived.
Photos make a great screensaver and the xscreensaver with glslideshow option is what I use. I often use it for ident practice, e.g. plants, birds etc. The image appears randomly on the screen and I think, I know what that is…
At the moment I have various scripts that can create ad-hoc collections of images based on the embedded tags. I also overlay a caption over the images using the convert bit of imagemagick and that works well.
What I want to do is have a time delay so that an image appears for say, 10 seconds, and then a caption appears over it. The filename would be ok. I can control how long the image appears in xscreensaver, and it’s surprisingly easy to train yourself to not-look at the filename or caption, but I’m curious as to whether it’s possible (without too much effort) to add the caption after some time-out period.
