36. Virtual reality (stalled at the description stage...) - "custom clone" of Secondlife.com
37. Virtual reality - Generated worlds. Alive :-).
38. Object's 360 degree view - "turnoramas" of small or heavy objects.
39. Panoramas - 360 degree panoramas of Nature and indoor rooms. Some people call them "virtual tours" too.
40. Special effects - Well, just combinations of several techniques... :-) Right now only two samples remain, others are difficult to show online, but I will do later this too.
41. The Exchanger - an exchanger for virtual currencies. The project was delayed by the owner and then died, but I keep it here out of nostalgia. Not many functions, compared to the scripts below. It has 3 areas (Public, Member's and Admin's, last two areas - protected by passwords), own captcha solution. Multilingual "by any viewpoint" - pages, emails, Admin area - everything, languages can always be changed. "Change the language" buttons/links are customizable, also can be horizontal or vertical. It has 65 HTML pages, all templates. Around 70 PHP scripts, MySQL database with 5 tables. Also it is created to be "difficult to crack", because it works with money directly.
42. AG Selena - a hospital, specialized in childbirth and pregnancy care, pregnancy problems, "in vitro" artificial pregnancy. Nice inside 360 degree panoramas. All HTML, some Flash and JavaScript.
43. Brothers Security - Security escort and armed guarding agency. HTML and JavaScript.
44. KC's Keyboard - (not online) an HTML on-screen keyboard, created for PhotoStation project (see below). Designed for Mozilla, may also work with other browsers too.
45. PhotoStation - a Kiosk-like multilingual photo extractor and printer machine, it can't be shown online, where I do some basic graphic transformations. Contains 10 HTML pages, 5 JavaScripts, 10 Perl scripts, 5 shell (bash) scripts.
46. Algarve-Rental - most complicated project. It is created for a middle-man in car hiring business. Site allows calculations of rental sums "on the fly", creating of customer accounts, a points system that provides discounts for returning customers, promotion's codes, search engine and many other functions. Has 4 areas (Visitors, Members, Operators, Admins; search engine works for both), last 3 - password protected. Uses a way to show URLs, always ending with ".html" (because of search engines), other URLs that hide their content with custom coding system (because of competitors :-) and mix of these two types of URLs too. Additionally it creates "email-friendly" (short) URLs, when needed. Works with my own template engine, contains 80-100 HTML pages. MySQL database contains many tables (16) and needs complex and well-tuned queries. All this are served by over 80 Perl scripts. Right now goes "SEO optimization" and "multilingualisation" of the site...
47. PR PopOver - a pop-up ad window, generated by JavaScript code inside HTML pages, contains "creator" page, where the exact ad can be constructed. Uses layers, works with IE, Netscape, Mozilla, Opera and compatible browsers.
48. Maria Pavlova (and blog, and a book) - Writer's private site, with all the works online.
49. AntHill - my favourite. Can't be shown online. A distributed computer system, based on usual WEB tools - HTTP server and Perl language. Think of it as of predecessor of Hadoop. "The Queen" (main server) sends pieces of jobs to "the Workers", so many small computers act like one large computer - cheaper way to have supercomputer. Best for batch tasks. Very scalable, very powerful and very flexible - can calculate weight of stars, browse the entire WEB or generate (render) video clips. And all these and other tasks simultaneous. Simply need to create the required “ant” software. Works the same way like the system, used with reading of human DNA. This is the technology behind the screensaver mentioned below.
50. EzySuccess - (already not in use) a self-replicated MLM site with 3 areas (Public, Member's and Admin's, last two of them - protected by passwords), personalized Opt-In list for admins and many other features, around 30 HTML pages, around 30 Perl scripts, MySQL database

This is an MLM community of 170,000 members and it grows with approx. 100 members daily. Most pages are templated by special tags. It has online payment system with two (soon - more) payment processors, commission calculation "on fly", tons of functions in Member's and Admin area, it sends more than 2 million emails daily. This site uses 7 servers (but we will add new server soon - we need more power, site grows very fast) and me and a friend of mine (system admin) support and develop this site. Next "subproject" (finished, but never launched) to AdSaturation are a Windows screen saver, just like the SETI@home's one, but it will send emails, instead of analysing Space signals.
