In case it’s not clear there are YouTube links for all the demos so you don’t need to build and run them.
I must be blind; where are those YouTube links?
If you click through to the individual demo pages it’s on the right. Not all of them are videos and not all the videos have YouTube links though.
No graphics tag on demoscene stuff? For shame. :P
