	Curve Pilot for Mac | License: Demo |
	Curve Pilot designed for teaching the basics of color corrections of images created by a digital camera or scanner. The traditional image editors use the curve method for color correction. The drawback of this method is that you don't always understand in which direction you should move certain curve. Curve Pilot offers you a revolutionary new method: simply indicate which color you want to get as a result of color correction and Curve Pilot will automatically calculate the values for curves that allow you to achieve the goal. It will show the curves on the screen and perform color correction. The corrected images can be saved in the JPEG or TIFF formats and the curves can be used for the fine tune-up in another editor, Adobe Photoshop, for example.

	GoldenGem | License: Freeware |
	Review: This program is considered to be one of the best of the neural network stock prediction programs. It is probably based on, or at least is named after the original 'goldengem' consoles, which are rarely seen nowadays. The usual disadvantage of a neural network is that it's not easy to tell whether or how it is working. By pressing essentially one button to update your shares, and a second button called 'Run/Pause,' you are brought to a sort of oscilloscope display. The vertical slider to the left of the display flashes insistently. . As it is raised upwards, the horizontal green line on the graph (indicating zero) jumps to life.

	Crickler | License: Freeware |
	Cricklers are a new type of word puzzle - a total re-invention of the crossword puzzle for the computer age. Traditional crossword puzzles are incredibly successful but they have several serious drawbacks: (1) They are difficult to construct, (2) Most words are short and often silly -- chosen only because they fit, (3) Matching clues to numbers is a distraction, and (4) A given puzzle is usually either too easy or too hard. Cricklers solve all of these problems while retaining the essence and feel of a traditional crossword puzzle. Cricklers adapt: they become easier or harder depending on the skill of the solver.
