I use a Perl script to generate slides as a set of linked HTML pages. There's a version of the script (and various themes) here and an example slide set using a plain theme here.

The slide template includes a JavaScript snippet so you can just press the space bar to advance to the next slide (no mucking round clicking on links).

The script uses Text::VimColor to syntax highlight code samples. And of course if you have additional requirements, it's Perl so you can hack it yourself.

Note: although HTML slides are extremely easy to publish on the web, ironically they're not supported by the Slideshare site.
