What the C*lor!

When doing web design you have to figure out the best color, e.g. for the page background. Using a WYSIWYG editor this would be no problem. But I personally don’t like them. So I have to either first design the page in another app like InkScape and then use the same color, or I have to commit myself to trial and error — this is painful!

This is where ”What the C*lor!” jumps in.

“What the C*lor” let’s you adjust the text, background and border color of any element, specified by a CSS selector. It uses jQuery and Farbtastic.

How to use:

Since “What the C*lor” is a bookmarklet, you only need to bookmark the following link — simply drag it into your bookmarks bar:

What the C*lor!

Type the selector for the element you want to style into the selector box (It uses jQuery to find the element, so you can also use selectors like :odd. Then you can use the color wheel to adjust the colors of the element. When you found the right color, copy the color from the text field below the color wheel. I hope you can find it useful.

Inversion

I had to make an app that solves the problem of Apollonius about half a year ago, so I'm publishing it here in case someone needs it.

Now for those of you who don't know what the problem of Apollonius is: It's about geometry, or more precisely Euclidean plain geometry. The task is to construct all circles (or lines) that are tangent to ("touch") three circles (or a point / line).

Now this may sound easy, but try to do this with three points, which is the most easy one (as much as I remember). You'll soon find out it isn't that easy. But if you use something called "inversion" (not the app), it's very easy. Inversion is sometimes also called "mirroring in a circle" (at least in German), which explains the concept very well (google for it if you want).

This is my first app (other than web apps), so don't expect too much of it. But still it's fun to play around. It's free and I'll give you the source code if you want (I'm not good at choosing copyleft licenses, so I'd appreciate advise).

Download:

Inversion1.1.dmg

How to use:

Add shapes with the plus button on the bottom left of the window. You can change the properties of the shapes using the inspector. If you have 3 shapes, the solution of the problem of Apollonius will be drawn in red.

• Mac OS 10.5 Leopard (Universal)
