An as close as possible copy of the IFTTT onboarding experience. This prototype is also made in 4 other tools (Pixate, Origami, Framer & Form) to compare the differences between them.

A mobile app that aggregates pricing data for video games to help the user find the best deal possible. This was created as a project for a class on prototyping techniques.

This prototype is addressing the payment portion of the Car2go app. The current mobile app has no options to manage any payment information. Use the blue car icons or the hamburger navigation to view the proposed payment portion.

Hello, I ca't seem to get this working, so I made it a challenge: Photoshop-like dynamic zoom with Right-Mouse-Button Drag with Left Mouse Button - To Pan in all directions - Make sure Inertia still works Drag with Right Mouse Button - To the right to zoom in - To the left to zoom out Extra points - Realtime fluent zooming - Center the zoom around the first point you click on with the mouse I am very curious as to if this is possible... regards, Koen van NIekerk
