I have created lots of software programs using PERL and javascript, such as:

• an ad-ticker that sits at the bottom of the screen
• an "Accept Cookies" screen that locks the browser till they accept
• CB-Wizard: Allows you to do many things, including add a ClickBank search engine to website
• Listbot Wizard: A couple of unique twists on the mailing list idea
• Poppa Banner that allows you to display banner ads that also add people to your mailing list

As of September 2013, I'm making a concerted effort to put all these programs online again

I've also got a unique membership site concept coming up soon using my Web20SiteMakerPro software. Basically, "co-admin" agree to upload two articles / videos a month, and in return get to keep 100% of any monthly membership fees they obtain. (I get a small retainer from each co-admin each month roughly equal to ONE paid membership)
