My Laptop :
OS : Vista Ultimate SP1
Memory : 1GB Memory
CPU : Intel T2300 @ 1.66GHz (2 CPU's, Duel Core), ~1.7GHz
Graphics : Mobile Intel® 945 Express Chipset 251MB (Though irrelevant as it's not used with my program)

Stage 1 on my Raytracer coded in VBA (Visual Basic for Applications). For the record, it's like a shitty version of Visual Basic 6...which in itself is laughed at for not being a real programming language!
This was a lot harder to make than you might think, it involved a reasonable chunk of API code, and "StdPictures". :X

It took 32 milliseconds overall from creation of variables too finishing preparation of the picture. It took less than a millisecond (my program says 0) to fill the array with random RGB values o..o
The array was handled with the "SetBitmapBit" API.
