When I saw this had been updated to a full point version I freaked out. This has been such a useful tool for me to show web designers I work with how important it is to not rely solely on color to differentiate action items. So I was very excited to see it is still being maintained. In the current version I am unable to resize from the corners of the window. Try to drag from the corner and you select the item behind the window. Resizing from left, right and bottom size work but it means more effort to get the window to the size you want. It would be great to see a full-screen option that shows the entire screen in the selected filter.

I showed my boss the new FileMaker app I had created for the lab, and he said: "Could you add this info?" which was right there in front of him - that's when I realized he is red/green blind and simply couldn't see the writing. I found Sim Daltonism and since then haven't created an app, a web page, or a presentation without first checking it with Sim Daltonism. Essential app in my opinion.

Really nice application. I’ve used in the past to test how website designs work for color-blind people. It always worked great and I really appreciate the update after nearly four years, so I could continue to use SimDaltonsim in the future.

Brilliant. Very useful for web designers who are into standards compliancy and accessibility (ie. who are into designing properly). Well done.

initial launch of your app on a Powerbook G3 Pismo with 640MB RAM running in millions of colors: "incompatible cpu-subtype". apparently your app is has more needs than just 10.3 and millions of colors.

Cute. A problem, though. When the display window "Funhouses" (Move the view to the window itself... much like in the sample picture), it starts to chug majorly. I made the mistake of hitting the button to maximize the window size in an (admittedly foolish) attempt to basically get a more firsthand feeling, where my entire screen would be under the effect. While my whole screen was indeed colorblind, the problem is that Sim Daltonism is showing Sim Daltonism showing Sim Daltonism showing Sim Daltonism. The screen immediately filled up with menubars and the display window lagged to high hell. Fortunately, the window functions were still passably responsive and I set the window back to its original size without having to force quit the program or otherwise having it crash. I think it definitely needs some optimization so it doesn't lag so easily, and it should preferably not show its own window in the display On the more positive side though: - It didn't crash during aforementioned full-screen funhousing - It's an interesting concept - The fact that I can make more than one window and set the filters independently is great.

Githon, while it would be great if I could take an screenshot of what is behind the window so that Sim Daltonism doesn't show its own windows recursively, I don't think that to be possible. However, I could arrange it so that you see a blank rectangle instead. This would be less distracting. As for speed, it was too slow some months ago, now it's fine so I can publish it, but it could still be improved. This software is free, but improvements will surely come sooner if I receive some donations. Thank you for this insithful comment.

Only now do I find your response :) I think a blank rectangle instead of the recursive effect would drastically increase performance, since the funhousing seems to be what makes it chug anyway.
