LightBulb
Adjust screen gamma to match the time of day

LightBulb is a f.lux-like application which smoothly adjusts screen gamma to make colours seem warmer at night, reducing eye strain and making your PC more comfortable to use.

Install the program and it goes to work automatically, detecting your location, figuring out the sunrise and sunset time and updating your display colour temperature accordingly.

Right-clicking the LightBulb icon in your system tray and selecting "Configure" displays some useful options and tools. To get started, click the "Preview 24-hour cycle" icon and watch as the program shows you how your display colour temperature will change over time. If that's too much, or too little, use the sliders to adjust the daytime and night time colour temperatures and hit Preview to see the change.

Elsewhere, a "Gamma Polling" option refreshes the current gamma settings every five seconds, handy if another application tries to change them.

If you'd prefer other applications to be able to take control, Gamma Polling can be disabled, and it's also possible to disable the effect when a full screen application is in the foreground.

If this causes problems at any time - maybe you're editing graphics and need to see colours as they really are - the effect can be disabled in a click or two, either entirely or for a defined period of time. Alternatively,  close the program at any time and your screen will immediately return to normal.

v1.6.3.2 (Changelog):

Added smooth UI transitions between tabs
Fixed incorrect color zoning in some parts of the main window
Other very minor design cleanups and improvements

Verdict:

LightBulb seems to be finding your location by using your external IP address, which might be a problem if you're using a VPN. But otherwise it's a likeable and configurable tool which really can make your monitor more comfortable to read.

Unreal Engine 4.15.1

Free Full Commercial Software

Unreal Engine is Epic Games' game engine, a powerful suite of tools for developing anything from basic 2D games to professional RPGs, first person shooters and whatever else you like.

Wide standards support - DirectX, OpenGL, JavaScript/ WebGL - means your projects can be targeted to almost any platform: consoles, iOS, Android, Windows, OS X, Linux, HTML5 browsers and more.

There's a vast amount to learn, of course, and that's even before you start building your game. But there's plenty of documentation, tutorials, demos and sample projects to point you in the right direction.

The package is now entirely free, too - no annoying limitations, nag screens or anything else. Epic now only requires that you pay a 5% royalty after the first $3,000 of revenue per product per quarter. And even then, you "pay no royalty for film projects, contracting and consulting projects such as architecture, simulation and visualization."
