To register Spirofractal please do the following:
Click on the Register Button in the Screen Saver Settings, (or select the Register command from the main program, or the Spirofractal icon in Start Menu if you installed the full program), and note down the 9 letter code given there, or, to make life easier for yourself, answer yes when asked if you would like to copy the code to the clipboard. The Help, About option in Spirofractal.exe also shows this code.
You can order a Spirofractal registration online and pay by credit card. Make sure you enter the correct 9 letter code in the appropriate field when you order, and supply an e-mail address to which I can send you an e-mail with an attachment, otherwise I won't be able to process your order. You can paste the 9 letter code from the clipboard by pressing Ctrl+V (assuming you copied it there as described above). You are strongly recommended to supply the code this way, otherwise you are quite likely to get it wrong, as I have found to my cost! Click here to order Spirofractal online.
If you do not want to use the online order facility then please send an e-mail to alunw@freeuk.com stating that you wish to register Spirofractal and quoting your 9 character ID code, and explaining how you intend to pay. If you copied the code to the clipboard you can paste the code into your e-mail by pressing Ctrl+V. Please send the e-mail from an address where I can send you a reply with an attachment. The attachment will be a text file needed to complete the registration process. Send a cheque or money order for £7 (GBP) to the following address:
The registered version uses a random number generator with over 4.000,000,000 possible combinations,which can be cycled through in over 4,000,000,000 different ways (though the number of possible patterns is far more than this because there are other factors which influence what happens on screen). In the unregistered version there are only 8 starting combinations, and the random number generator is limited to 4096 numbers altogether, which are cycled though in a fixed order, all of which will drastically reduce the number of patterns.
The registered version does not have nag messages, or the limitations described in the next paragraph.
The unregistered version will not allow pictures to be added to the gallery, and you cannot return to earlier pictures with the undo/back facility. You cannot suppress Wolfram Cellular Automata. When you save an image it will have a black cross across the centre. The program will quit after fifteen minutes, and won't run again until you reboot. (The screen saver will continue to run after fifteen minutes but the images will shrink, and some image types will stop being used. The transitions will be disabled, as will true color images.).
Registered users will be entitled to free upgrades of Spirofractal. Possible future upgrades are an option to generate music from an image, or images in time to CDs or MP3s being played on your computer.
The author will be encouraged to write more and better shareware! If you want development of Spirofractal to continue you should register. If large numbers of people continue to download Spirofractal without registering it future unregistered versions will have more features crippled. Don't force me to force you to be honest.
Registration is specific to an individual computer, and the registered version must not be given to others. In most cases the registered version will not work if copied onto a different computer. If you upgrade or re-install Windows your registration may no longer be valid. To avoid this problem please make sure you keep the same registered owner each time you install Windows.
