This was a 7-day project, all the graphics was provided by the client. No canvas was used, the moving targets are implemented using html divs. This game has sound effects and background sound provided by the client and implemented by me using modern HTML5 sound engine. Features a mechanical-looking timer and mechanical volume knob that controls the sound volume. You can play the working demo here: http://wizstaff.com/airgun/

This was a Javascript/Webgl game project that I did in May 2016. It's an offline multiplayer yahtzee clone that can be played on a local computer or a tablet. The main difficulty was creating the 3d physics engine from scratch, collision detection and all that comes with it.No images were used in this project, all graphics was done using Webgl and CSS in divs on top of the Webgl canvas. You can check the playable demo at http://wizstaff.com/dice/

A Windows visual app written in C++/Qt that opens a file created by Finale Fireworks, checks all the firing Modules (custom produced by my employer) on the network and allows to connect them using module ID's. A sound file can be loaded, and a custom project file can be saved to disk. Also, the location of the venue can be looked looked up within the same app using Google Map (internet connection required), and colored rectangles can be used to mark Viewing areas, Firing positions. The modules can be assigned to firing positions. At a certain selected Time Zero, the show starts automatically (when the app is "armed"), and the UDP packets are dispatched to corresponding firing modules at exact moments according to the data from initial Finale Fireworks file. This project took me one month.

The Hurricane data is publicly awailable and it comes in the format similar to this page: http://www.nhc.noaa.gov/archive/2014/ep07/ep072014.discus.002.shtml and that website also provides its own visualization like so: http://www.nhc.noaa.gov/refresh/graphics_ep3+shtml/085122.shtml?5-daynl#contents My client wanted a google-map based visualization as well as the ability to easily test if a pair of coordinates is within the cone or not. Another part of the project was to be able to check given a pair of coordinates whether it is in a certain weather zone or not. The database of US weather zones is publicly available, but it is changes periodically, so a means of opening that database and using it to apply point-in-polygon algorithm was developed. All done in PHP+Javascript+JQUERY+CSS+Google maps API. The fact that Google maps does not correct lines to Earth curvature made this project even more difficult. Some advanced formulas needed to be applied for drawing the circle on the map
