Can't find topic related information, probably I am just asking wrong question.
For example I have configurable product, a T-Shirt.
I need to add some text on top of this T-Shirt, select size, colour, etc. Also I need to apply transformations to this text like distortion, rotation, etc.
Then I have to save this product in to the cart using my custom module. Also printer operator should be able to see all those parameters before printing t-shirt order.
What type of Magento product do I use? How do I add those products to cart? I need any related documentation and/or articles. Not source code :)
Thank you,
