DrawGen is a skydive generator for desktop computers.

Features:

• Generates skydives for 4-way, 8-way and the new VFS categories, all drawn from the NSL dive pools.
• Automatic generation of all categories by substitution. Generates a AAA draw, then removes inappropriate formations, (and adds new to create correct points requirement), to derive AA, A and Rookie dives (similarly for 8-way). Allows teams from lower categories to compare themselves against those above them.
• Manual mode - you can type in your skydive, and it will generate the pictures for you.
• Printing support (including print preview)!

The application creates skydives from the NSL dive pool (Rookie, 'A', 'AA' or 'AAA' classes for 4-way; Senior and Intermediate for 8-way) and gives the name and (optionally) a picture of each formation chosen. It has 3 modes of operation:

• Competition - Simulates a competition-type draw. A set of formations are drawn for a dive and left out of the 'pot', so they can't be drawn again.
• Continuous - Draws a set of formations for a dive and leaves them in the 'pot' so they can be drawn again.
• Formation display - Given a selected class (e.g. 'AA') this mode displays all the formations that are relevant to the class.

Bottles and Kegs is a drinking game. The game starts with one player giving a number and a direction in which to count (up or down). The next player then increments by one in that direction, and so on. The caveat is that if the next number has a 7 in it, or it is divisible by 7, you must say 'bottles' instead of the number; if the number has a 5 in it, or it is divisible by 5, you say 'kegs' instead of the number. If both apply (e.g. 35), then you should say 'bottles and kegs'. Any mistake results in a drinking penalty.

Obviously, this is fairly easy if the starting number is small, and dividing by 5 is trivial. But if someone starts at 321, it may not be obvious that the next number (322) is divisible by 7. This is an application that runs on a mobile phone, and solves the problem.
