wepidia is a set of two PHP files which allow you to browse through an entire picture collection, located in the same directory or in the subdirectories as the two files.

Other features include a location bar, customizable colors, and relocation of the layout.
X-Launch is a GTK based skinnable run dialog. It has bash style autocompletion, skin support, and animations to let you know when a slow application is launching. It can function like other run dialogs, but you can also tell it to stay resident in memory and hide itself after it launches an application.
(Multi-Agent) Transport Planner is a dynamic single agent transport planner for vehicle routing problems and dial-a-ride problems. These problems occur in every public transport and transportation company, but although some older algorithms can be found in the literature, a good implementation has never been published. It uses a (very quick) standard insertion technique to insert orders one by one into a set of routes.
CElect is a console-based tool for determining a social preference ordering, such as an elected candidate or choice in a single-winner election, or the preferred composition of a multi-member council, based on a list of individual preference orderings (ballots) over the candidates or choices. It can also calculate the winner and social ordering when given a Condorcet matrix and list of candidates, though it is in that case limited to Condorcet methods. Of single-winner methods, it supports Dodgson, Simpson, Tideman/wv, first and second-order Copeland, and Schulze (all Condorcet methods), and FPTP, Borda, 1/n Borda, Hare, Nanson, and 1/n Nanson. Of proportional representation, it supports CPO-STV, CFPRM, and D'Hondt without lists.
