I just released my first real app: Show Screen Lock.
Show Screen Lock acts just like other screen lock apps, except that it keeps the screen on!
For example, say you want to keep your shopping list app open while you are walking through the store, but don't want to worry about accidentally scrolling through the list or pressing a button you didn't mean to. Simply open Show Screen Lock and activate it through your Notification Bar and your screen locks, preventing touchscreen touches, while keeping the display on so you can see the app underneath.
Let me know what you guys think.
