People often ask me if I know of any demos that can be run from their hard drive. Most are obviously designed for floppy disks but there are many which can and many more which have been recently patched. So I have added an "HDD" tag on Demozoo for all the demos I have installed onto my hard drive and there are lots! :)
Of course, this is a work in progress so let me know if I've missed any... Clickety Click to enter Demozoo.
