These are some of the coolest login pages we have seen in Wisej projects. All of them were typical WinForms login dialogs with lots of complex logic behind them, but a very simple and traditional UI.
Our designer selected, cropped and positioned background images licensed from Shutterstock, always in relation to the type of application. Developers have reused the same WinForms dialog, arranged the controls, tuned the transparency, and adapted the theme to the design. The result is quite something.
The images below are for a large construction project management app, an enormous ERP for the packaging industry, and a complex intellectual property management app.
