Castlerama takes you on a photorealistic walk through a beautiful, detailed and accurately lit 3D setting. Merging real and imaginary elements, it draws inspiration from the charming town of Assisi, in Italy. You are left to find your own way around by touch and sight alone. Exploring a whole world becomes a matter of lifting your fingers. Our goal? To fool your eyes and brain considering it all real. When you go back with your memory to the day you first opened this Mentalbox, you will think it was you on the cobblestone, you in the alleys, you in the catacombs... While developing Castlerama, we had to face the fact that newer devices such as iPhone4s and iPad2s are very different from their predecessors, iPhone3GSs and iPads, in that the former have twice as much memory. In order to have the app run on all devices, we had to compromise quite a bit, pushing the old devices to their limits (risking crash if other applications are left running) while keeping the new devices well behind their capabilities. Powered by Unreal Engine.

POWERUP 4.0 is the smartest, most intuitive paper plane kit we’ve ever made. It makes it possible to fly with ease and smoothness in a variety of conditions. Say goodbye to nosedives and choppy flights. We’ve added a new on-board flight computer and 2 new sensors: gyro and accelerometer, combined with 2 thrust vectoring motors. That means flying POWERUP 4.0 is smoother than ever, and can now do all this: That’s right. POWERUP 4.0 can auto-loop. So you can master tricks and awesome aerobatics by simply pressing a button. We’ve added 2 high speed motors to POWERUP 4.0. That means you’ve got double the thrust, additional maneuvering possibilities, and sharper turns. And together with the flight assist, you can fly just about anything Now you can learn to fly like a pro. We’re showing you real-time analytics including heading direction, thrust level and turning angles. We’ve made it a lot easier and way cooler to fly POWERUP 4.0 at night. Optional LED lights will enable you to light up the night - making for awesome visuals and round-the-clock fun. 2 rear wheels and 1 front wheel give your paper plane more style and make for easier takeoff and landing. They also make it possible to launch off of a surface rather than hand-launching. We partnered with the best RC hobby vloggers on the planet – FliteTest! They have put together their incredibly creative minds to develop a foam jet inspired by the F22 for the 4.0. It is made from a special laser cut foam board they created and make in the USA. Intuitive control makes it easy to fly. Simply tilt your phone in the direction you want your plane to fly. It’s really that easy. POWERUP is an incredibly helpful tool when it comes to teaching and learning aeronautics. Students can test multiple designs, analyze their work and improve their planes. Through trial and error, they can understand what makes their plane fly smoother, longer and farther- key lessons in airplane design.
