The first one represents my role at the JISC RSC Scotland and the second my curriculum area before I became involved with technology. I had some ideas for the first one driving home - so didn't have a very systematic approach to the creative process as some of the more professional among us did.
For the second one I did some key word searches in image sites such as Flickr, Google images, MS Clipart online to get some ideas.
I used Photoshop to construct the basic images, some basic shapes tweaked from clipart online which has images you can use without breaching copyright. Actually I forgot how much I like using Photoshop (in a very basic way). I'd downloaded a new app to my iPad so I wanted to have a go at using it and transferred the images to it using Evernote - (a web service that enables you to share stuff between all the electronic devices you have - a great alternative to pen drives). The app I used to apply some effects and filters is called Pixlromatic. You open the image and there is a range of effects you can apply till you get the result you want.
Let me know if you can guess what my signs represent.
