We are experienced prototype engineers with thousands of hours designing and scripting prototypes and top rated video games. Hire us and put our years of experience to work for you. Let us turn your vision into an amazing high fidelity prototype that will get you noticed.


Tumblr has a very nice series of animations that happens when you enter the compose mode. I thought it would be interesting to recreate this in to show others how to achieve these kind of effect in their own protototypes. I have made a companion tutorial video where you can see exactly how I did it. This video is available here:


This prototype is a simulation of one part of the Pandora iPhone app. I have chosen to simulate the part of the app where the user selects a Pandora radio station and then proceeds to select that station. What I have demonstrated is how how the radio station animates from a small entry on a list to a large full screen entry and vice versa. If you would like to see how I created this prototype, please watch this video tutorial here:

10 Second Timer Example

I simulated a 10 second timer that counts down from 10 to 0. This is very simple to do. All you need to do is change the text property of the text value with a custom value and include a delay of 1 second. Then add a callback for the next number with a delay of 1 second. Repeat this until you get to the number 0. There is no need to use variables to simulate a timer. If you are looking for someone to help you with your prototype, we are available for hire at:

Carnival Shooting Gallery

This is a custom tablet prototype of my take on a popular carnival attraction called the shooting gallery. I wanted to show everyone how versatible and powerful the tool is and demonstrate that anyone can make video games using This prototype was inspired by various versions of the classic game created for mobile devices released a few years ago. This is meant for educational purposes only. Please click on the heart icon below to show your support and leave comments. I'd be happy to answer any questions you have. Have fun!

I created a prototype of the UBER app for Android in order to demonstrate what is possible using This project was a massive undertaking as my goal was to simulate the user experience of what it would be like to order 4 different UBER cars in San Francisco. I plan on doing a full "behind the scenes" article on my website about the challenges I faced along the way simulating the UBER app in Special thanks to the awesome team at for all of their tireless assistance along the way!
