Station Clock
Who doesn’t know what it’s like to wait for a train? The time refuses to go by yet the eyes stay glued to the second hand on the Station Clock. Slowly, steadily, the hand travels around the clock, then comes to a halt on the 12. For a brief moment time seems to stand still, but then the minute hand leaps forward and the second hand’s rotation starts all over again. Why this occurs and how you can display a completely individual station clock on your website can be read here…
Platonic solids
They have been known to mankind for over 4000 years. The 5 Platonic solids are perfect regular solids whose faces consist of equiangular and equilateral polygons of equal size.
The hour aglow
The Set Theory Clock, also known as the Berlin Clock, makes use of the principle of set theory to depict the time. The time of day is displayed in a 24-hour format and can be determined by simply adding and multiplying the glowing lights.
Let’s see, at the moment it’s glowing .
Background patterns for websites
During the early days of the Web background patterns were a popular means of sprucing up the pages on a website. Back then every webmaster had their own collection of more or less tasteful backgrounds. The patterns presented here stem from that time and can be tried out right away.
“Metamorphose II” by M.C. Escher
“Metamorphose II” by Maurits Cornelis Escher as an animated “woodcut strip”. The thirteen foot woodcut was in black, green and brown, printed from twenty-three blocks on three combined sheets.
Web application loan calculator
The idea for the loan calculator Web application ─ an RIA (Rich Internet Application) to be more precise ─ arose during an extensive IT project. The users enter loan queries in a Web front end. These are first handed over to a Java back end, then transferred from there to another server via CORBA (Common Object Request Broker Architecture). The loan is now calculated and travels the same route back. A process like this takes its time, of course, and errors of a technical or content nature can occur at any stage which must be communicated to the user. But in the end, why not let JavaScript calculate a loan in the browser?
iPhone App myReturn
The iPhone app myReturn originated at the end of 2009 for DONNER & REUSCHEL, a private bank. It can be obtained free of charge at the AppStore, at present only in German, and is targeted towards experienced users who can use the app to graphically illustrate the course of return for indices, commodities and shares, as well as for freely compiled portfolios.
An iPad version that also accommodates inexperienced users will be released soon.
