At DDD4 recently I saw Ben Lamb using a presentation aid called NLarge by Rob Burke. (You can download the binary here). NLarge is almost identical to ZoomIt by Mark Russinovich that I blogged about earlier this year. It is a tool for zooming and drawing on any screen. NLarge even uses the same activation keystrokes as ZoomIt. There are a few minor differences though. NLarge requires the .NET Framework 3.0 to be installed. NLarge’s magnify option is much smoother than ZoomIt’s and the speed of magnification is configurable (very useful). ZoomIt, however, has a Break option that NLarge lacks. On the whole both tools are very useful. I suspect that NLarge just pips ZoomIt for me because of the configurable magnification speed and the fact that I already have the .NET Framework 3.0 installed. If you don’t have the .NET Framework 3.0 installed then ZoomIt is probably a better option.
