Hi there!
I recently had to take a crash course in how to use the pen-tool in Photoshop as I was rusty, and so for practise I decided to re-create the Psygnosis logo (in blue tones) but in H.D. It came out much better than I had hoped and I have since modified it for use on the Eternal Psygnosis page on Facebook (a page for ex-employees and fans alike).
Here it is for you to see and download if you so wish.
Thanks for looking and I hope you like it.
And here's a link to the high-res version on my Deviantart page (click the image to enlarge):
